Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533756, here are decompositions:
- 97 + 31533659 = 31533756
- 157 + 31533599 = 31533756
- 193 + 31533563 = 31533756
- 223 + 31533533 = 31533756
- 239 + 31533517 = 31533756
- 257 + 31533499 = 31533756
- 307 + 31533449 = 31533756
- 347 + 31533409 = 31533756
Showing the first eight; more decompositions exist.
