Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544666, here are decompositions:
- 79 + 31544587 = 31544666
- 157 + 31544509 = 31544666
- 487 + 31544179 = 31544666
- 499 + 31544167 = 31544666
- 577 + 31544089 = 31544666
- 613 + 31544053 = 31544666
- 739 + 31543927 = 31544666
- 823 + 31543843 = 31544666
Showing the first eight; more decompositions exist.
