Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536736, here are decompositions:
- 3 + 31536733 = 31536736
- 5 + 31536731 = 31536736
- 17 + 31536719 = 31536736
- 29 + 31536707 = 31536736
- 107 + 31536629 = 31536736
- 197 + 31536539 = 31536736
- 353 + 31536383 = 31536736
- 383 + 31536353 = 31536736
Showing the first eight; more decompositions exist.
