Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539674, here are decompositions:
- 3 + 31539671 = 31539674
- 13 + 31539661 = 31539674
- 31 + 31539643 = 31539674
- 151 + 31539523 = 31539674
- 307 + 31539367 = 31539674
- 337 + 31539337 = 31539674
- 433 + 31539241 = 31539674
- 601 + 31539073 = 31539674
Showing the first eight; more decompositions exist.
