Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508380, here are decompositions:
- 7 + 508373 = 508380
- 13 + 508367 = 508380
- 17 + 508363 = 508380
- 31 + 508349 = 508380
- 53 + 508327 = 508380
- 79 + 508301 = 508380
- 83 + 508297 = 508380
- 107 + 508273 = 508380
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 508,380 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 508380 first appears in π at position 577,078 of the decimal expansion (the 577,078ordinal-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.
