Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497230, here are decompositions:
- 7 + 31497223 = 31497230
- 43 + 31497187 = 31497230
- 73 + 31497157 = 31497230
- 97 + 31497133 = 31497230
- 103 + 31497127 = 31497230
- 223 + 31497007 = 31497230
- 229 + 31497001 = 31497230
- 241 + 31496989 = 31497230
Showing the first eight; more decompositions exist.
