Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525730, here are decompositions:
- 7 + 31525723 = 31525730
- 13 + 31525717 = 31525730
- 31 + 31525699 = 31525730
- 43 + 31525687 = 31525730
- 73 + 31525657 = 31525730
- 79 + 31525651 = 31525730
- 127 + 31525603 = 31525730
- 163 + 31525567 = 31525730
Showing the first eight; more decompositions exist.
