Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625206, here are decompositions:
- 59 + 31625147 = 31625206
- 149 + 31625057 = 31625206
- 167 + 31625039 = 31625206
- 227 + 31624979 = 31625206
- 443 + 31624763 = 31625206
- 467 + 31624739 = 31625206
- 563 + 31624643 = 31625206
- 593 + 31624613 = 31625206
Showing the first eight; more decompositions exist.
