Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544232, here are decompositions:
- 11 + 31544221 = 31544232
- 19 + 31544213 = 31544232
- 43 + 31544189 = 31544232
- 53 + 31544179 = 31544232
- 61 + 31544171 = 31544232
- 79 + 31544153 = 31544232
- 101 + 31544131 = 31544232
- 179 + 31544053 = 31544232
Showing the first eight; more decompositions exist.
