Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542990, here are decompositions:
- 3 + 542987 = 542990
- 43 + 542947 = 542990
- 67 + 542923 = 542990
- 79 + 542911 = 542990
- 193 + 542797 = 542990
- 199 + 542791 = 542990
- 229 + 542761 = 542990
- 271 + 542719 = 542990
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 542,990 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
