Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544464, here are decompositions:
- 47 + 31544417 = 31544464
- 71 + 31544393 = 31544464
- 101 + 31544363 = 31544464
- 167 + 31544297 = 31544464
- 251 + 31544213 = 31544464
- 257 + 31544207 = 31544464
- 293 + 31544171 = 31544464
- 311 + 31544153 = 31544464
Showing the first eight; more decompositions exist.
