Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130624, here are decompositions:
- 3 + 130621 = 130624
- 5 + 130619 = 130624
- 71 + 130553 = 130624
- 101 + 130523 = 130624
- 107 + 130517 = 130624
- 167 + 130457 = 130624
- 257 + 130367 = 130624
- 281 + 130343 = 130624
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 130,624 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 130624 first appears in π at position 904,034 of the decimal expansion (the 904,034ordinal-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.
