Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545144, here are decompositions:
- 47 + 31545097 = 31545144
- 53 + 31545091 = 31545144
- 61 + 31545083 = 31545144
- 83 + 31545061 = 31545144
- 181 + 31544963 = 31545144
- 317 + 31544827 = 31545144
- 373 + 31544771 = 31545144
- 431 + 31544713 = 31545144
Showing the first eight; more decompositions exist.
