Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525722, here are decompositions:
- 5 + 31525717 = 31525722
- 23 + 31525699 = 31525722
- 71 + 31525651 = 31525722
- 73 + 31525649 = 31525722
- 113 + 31525609 = 31525722
- 223 + 31525499 = 31525722
- 233 + 31525489 = 31525722
- 379 + 31525343 = 31525722
Showing the first eight; more decompositions exist.
