Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508800, here are decompositions:
- 11 + 508789 = 508800
- 29 + 508771 = 508800
- 73 + 508727 = 508800
- 107 + 508693 = 508800
- 139 + 508661 = 508800
- 157 + 508643 = 508800
- 163 + 508637 = 508800
- 179 + 508621 = 508800
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 508,800 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 508800 first appears in π at position 145,890 of the decimal expansion (the 145,890ordinal-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.
