Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995240, here are decompositions:
- 3 + 995237 = 995240
- 13 + 995227 = 995240
- 67 + 995173 = 995240
- 73 + 995167 = 995240
- 277 + 994963 = 995240
- 307 + 994933 = 995240
- 313 + 994927 = 995240
- 373 + 994867 = 995240
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 995,240 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 995240 first appears in π at position 26,897 of the decimal expansion (the 26,897ordinal-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.
