Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486262, here are decompositions:
- 61 + 31486201 = 31486262
- 139 + 31486123 = 31486262
- 229 + 31486033 = 31486262
- 331 + 31485931 = 31486262
- 373 + 31485889 = 31486262
- 439 + 31485823 = 31486262
- 463 + 31485799 = 31486262
- 541 + 31485721 = 31486262
Showing the first eight; more decompositions exist.
