Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497060, here are decompositions:
- 53 + 31497007 = 31497060
- 59 + 31497001 = 31497060
- 71 + 31496989 = 31497060
- 83 + 31496977 = 31497060
- 97 + 31496963 = 31497060
- 103 + 31496957 = 31497060
- 113 + 31496947 = 31497060
- 139 + 31496921 = 31497060
Showing the first eight; more decompositions exist.
