Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505120, here are decompositions:
- 3 + 505117 = 505120
- 23 + 505097 = 505120
- 29 + 505091 = 505120
- 47 + 505073 = 505120
- 53 + 505067 = 505120
- 59 + 505061 = 505120
- 71 + 505049 = 505120
- 89 + 505031 = 505120
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 505,120 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
