Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522200, here are decompositions:
- 19 + 31522181 = 31522200
- 71 + 31522129 = 31522200
- 97 + 31522103 = 31522200
- 109 + 31522091 = 31522200
- 139 + 31522061 = 31522200
- 179 + 31522021 = 31522200
- 181 + 31522019 = 31522200
- 223 + 31521977 = 31522200
Showing the first eight; more decompositions exist.
