Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527738, here are decompositions:
- 29 + 31527709 = 31527738
- 37 + 31527701 = 31527738
- 41 + 31527697 = 31527738
- 61 + 31527677 = 31527738
- 79 + 31527659 = 31527738
- 197 + 31527541 = 31527738
- 239 + 31527499 = 31527738
- 241 + 31527497 = 31527738
Showing the first eight; more decompositions exist.
