Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522128, here are decompositions:
- 37 + 31522091 = 31522128
- 67 + 31522061 = 31522128
- 107 + 31522021 = 31522128
- 109 + 31522019 = 31522128
- 137 + 31521991 = 31522128
- 149 + 31521979 = 31522128
- 151 + 31521977 = 31522128
- 241 + 31521887 = 31522128
Showing the first eight; more decompositions exist.
