Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513844, here are decompositions:
- 3 + 513841 = 513844
- 5 + 513839 = 513844
- 83 + 513761 = 513844
- 113 + 513731 = 513844
- 251 + 513593 = 513844
- 311 + 513533 = 513844
- 491 + 513353 = 513844
- 503 + 513341 = 513844
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 513,844 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 513844 first appears in π at position 209,120 of the decimal expansion (the 209,120ordinal-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.
