Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479520, here are decompositions:
- 7 + 479513 = 479520
- 11 + 479509 = 479520
- 23 + 479497 = 479520
- 31 + 479489 = 479520
- 47 + 479473 = 479520
- 59 + 479461 = 479520
- 79 + 479441 = 479520
- 89 + 479431 = 479520
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 479,520 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
