Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545146, here are decompositions:
- 79 + 31545067 = 31545146
- 97 + 31545049 = 31545146
- 223 + 31544923 = 31545146
- 397 + 31544749 = 31545146
- 433 + 31544713 = 31545146
- 613 + 31544533 = 31545146
- 823 + 31544323 = 31545146
- 967 + 31544179 = 31545146
Showing the first eight; more decompositions exist.
