Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463890, here are decompositions:
- 11 + 31463879 = 31463890
- 41 + 31463849 = 31463890
- 47 + 31463843 = 31463890
- 83 + 31463807 = 31463890
- 131 + 31463759 = 31463890
- 173 + 31463717 = 31463890
- 383 + 31463507 = 31463890
- 401 + 31463489 = 31463890
Showing the first eight; more decompositions exist.
