Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544906, here are decompositions:
- 7 + 31544899 = 31544906
- 79 + 31544827 = 31544906
- 157 + 31544749 = 31544906
- 193 + 31544713 = 31544906
- 373 + 31544533 = 31544906
- 397 + 31544509 = 31544906
- 727 + 31544179 = 31544906
- 739 + 31544167 = 31544906
Showing the first eight; more decompositions exist.
