Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544872, here are decompositions:
- 53 + 31544819 = 31544872
- 89 + 31544783 = 31544872
- 101 + 31544771 = 31544872
- 113 + 31544759 = 31544872
- 311 + 31544561 = 31544872
- 479 + 31544393 = 31544872
- 509 + 31544363 = 31544872
- 659 + 31544213 = 31544872
Showing the first eight; more decompositions exist.
