Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461150, here are decompositions:
- 23 + 31461127 = 31461150
- 37 + 31461113 = 31461150
- 101 + 31461049 = 31461150
- 103 + 31461047 = 31461150
- 113 + 31461037 = 31461150
- 137 + 31461013 = 31461150
- 139 + 31461011 = 31461150
- 173 + 31460977 = 31461150
Showing the first eight; more decompositions exist.
