Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031220, here are decompositions:
- 31 + 1031189 = 1031220
- 59 + 1031161 = 1031220
- 79 + 1031141 = 1031220
- 83 + 1031137 = 1031220
- 101 + 1031119 = 1031220
- 103 + 1031117 = 1031220
- 139 + 1031081 = 1031220
- 163 + 1031057 = 1031220
Showing the first eight; more decompositions exist.
