Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520248, here are decompositions:
- 7 + 520241 = 520248
- 97 + 520151 = 520248
- 137 + 520111 = 520248
- 181 + 520067 = 520248
- 227 + 520021 = 520248
- 229 + 520019 = 520248
- 251 + 519997 = 520248
- 277 + 519971 = 520248
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 520,248 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 520248 first appears in π at position 112,493 of the decimal expansion (the 112,493ordinal-suffix:rd 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.
