Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527708, here are decompositions:
- 5 + 31527703 = 31527708
- 7 + 31527701 = 31527708
- 11 + 31527697 = 31527708
- 19 + 31527689 = 31527708
- 31 + 31527677 = 31527708
- 131 + 31527577 = 31527708
- 139 + 31527569 = 31527708
- 167 + 31527541 = 31527708
Showing the first eight; more decompositions exist.
