Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544226, here are decompositions:
- 5 + 31544221 = 31544226
- 13 + 31544213 = 31544226
- 19 + 31544207 = 31544226
- 37 + 31544189 = 31544226
- 47 + 31544179 = 31544226
- 59 + 31544167 = 31544226
- 73 + 31544153 = 31544226
- 127 + 31544099 = 31544226
Showing the first eight; more decompositions exist.
