Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492032, here are decompositions:
- 43 + 31491989 = 31492032
- 73 + 31491959 = 31492032
- 139 + 31491893 = 31492032
- 151 + 31491881 = 31492032
- 191 + 31491841 = 31492032
- 239 + 31491793 = 31492032
- 241 + 31491791 = 31492032
- 283 + 31491749 = 31492032
Showing the first eight; more decompositions exist.
