Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621094, here are decompositions:
- 13 + 31621081 = 31621094
- 31 + 31621063 = 31621094
- 61 + 31621033 = 31621094
- 67 + 31621027 = 31621094
- 151 + 31620943 = 31621094
- 157 + 31620937 = 31621094
- 163 + 31620931 = 31621094
- 223 + 31620871 = 31621094
Showing the first eight; more decompositions exist.
