Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488720, here are decompositions:
- 3 + 488717 = 488720
- 19 + 488701 = 488720
- 31 + 488689 = 488720
- 79 + 488641 = 488720
- 103 + 488617 = 488720
- 109 + 488611 = 488720
- 181 + 488539 = 488720
- 313 + 488407 = 488720
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 488,720 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
