Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540744, here are decompositions:
- 17 + 31540727 = 31540744
- 101 + 31540643 = 31540744
- 107 + 31540637 = 31540744
- 113 + 31540631 = 31540744
- 251 + 31540493 = 31540744
- 401 + 31540343 = 31540744
- 503 + 31540241 = 31540744
- 563 + 31540181 = 31540744
Showing the first eight; more decompositions exist.
