Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510120, here are decompositions:
- 19 + 510101 = 510120
- 31 + 510089 = 510120
- 41 + 510079 = 510120
- 43 + 510077 = 510120
- 47 + 510073 = 510120
- 53 + 510067 = 510120
- 59 + 510061 = 510120
- 71 + 510049 = 510120
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 510,120 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 510120 first appears in π at position 484,300 of the decimal expansion (the 484,300ordinal-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.
