Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533592, here are decompositions:
- 5 + 31533587 = 31533592
- 11 + 31533581 = 31533592
- 29 + 31533563 = 31533592
- 59 + 31533533 = 31533592
- 131 + 31533461 = 31533592
- 179 + 31533413 = 31533592
- 383 + 31533209 = 31533592
- 401 + 31533191 = 31533592
Showing the first eight; more decompositions exist.
