Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516250, here are decompositions:
- 13 + 31516237 = 31516250
- 61 + 31516189 = 31516250
- 67 + 31516183 = 31516250
- 97 + 31516153 = 31516250
- 127 + 31516123 = 31516250
- 151 + 31516099 = 31516250
- 163 + 31516087 = 31516250
- 223 + 31516027 = 31516250
Showing the first eight; more decompositions exist.
