Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540692, here are decompositions:
- 13 + 31540679 = 31540692
- 23 + 31540669 = 31540692
- 41 + 31540651 = 31540692
- 61 + 31540631 = 31540692
- 163 + 31540529 = 31540692
- 191 + 31540501 = 31540692
- 193 + 31540499 = 31540692
- 199 + 31540493 = 31540692
Showing the first eight; more decompositions exist.
