Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544422, here are decompositions:
- 5 + 31544417 = 31544422
- 29 + 31544393 = 31544422
- 59 + 31544363 = 31544422
- 233 + 31544189 = 31544422
- 251 + 31544171 = 31544422
- 269 + 31544153 = 31544422
- 383 + 31544039 = 31544422
- 389 + 31544033 = 31544422
Showing the first eight; more decompositions exist.
