Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539946, here are decompositions:
- 83 + 31539863 = 31539946
- 89 + 31539857 = 31539946
- 107 + 31539839 = 31539946
- 233 + 31539713 = 31539946
- 239 + 31539707 = 31539946
- 353 + 31539593 = 31539946
- 359 + 31539587 = 31539946
- 479 + 31539467 = 31539946
Showing the first eight; more decompositions exist.
