Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018624, here are decompositions:
- 3 + 1018621 = 1018624
- 11 + 1018613 = 1018624
- 41 + 1018583 = 1018624
- 311 + 1018313 = 1018624
- 353 + 1018271 = 1018624
- 401 + 1018223 = 1018624
- 617 + 1018007 = 1018624
- 701 + 1017923 = 1018624
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,018,624 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 1018624 first appears in π at position 580,544 of the decimal expansion (the 580,544ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
