Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544718, here are decompositions:
- 5 + 31544713 = 31544718
- 61 + 31544657 = 31544718
- 131 + 31544587 = 31544718
- 157 + 31544561 = 31544718
- 167 + 31544551 = 31544718
- 347 + 31544371 = 31544718
- 421 + 31544297 = 31544718
- 547 + 31544171 = 31544718
Showing the first eight; more decompositions exist.
