Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580736, here are decompositions:
- 17 + 31580719 = 31580736
- 43 + 31580693 = 31580736
- 53 + 31580683 = 31580736
- 59 + 31580677 = 31580736
- 67 + 31580669 = 31580736
- 179 + 31580557 = 31580736
- 197 + 31580539 = 31580736
- 233 + 31580503 = 31580736
Showing the first eight; more decompositions exist.
