Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523570, here are decompositions:
- 31 + 31523539 = 31523570
- 97 + 31523473 = 31523570
- 103 + 31523467 = 31523570
- 109 + 31523461 = 31523570
- 151 + 31523419 = 31523570
- 163 + 31523407 = 31523570
- 223 + 31523347 = 31523570
- 241 + 31523329 = 31523570
Showing the first eight; more decompositions exist.
