Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456134, here are decompositions:
- 11 + 31456123 = 31456134
- 13 + 31456121 = 31456134
- 41 + 31456093 = 31456134
- 67 + 31456067 = 31456134
- 113 + 31456021 = 31456134
- 131 + 31456003 = 31456134
- 173 + 31455961 = 31456134
- 233 + 31455901 = 31456134
Showing the first eight; more decompositions exist.
