Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523370, here are decompositions:
- 23 + 31523347 = 31523370
- 41 + 31523329 = 31523370
- 61 + 31523309 = 31523370
- 103 + 31523267 = 31523370
- 127 + 31523243 = 31523370
- 139 + 31523231 = 31523370
- 149 + 31523221 = 31523370
- 163 + 31523207 = 31523370
Showing the first eight; more decompositions exist.
