Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525782, here are decompositions:
- 5 + 31525777 = 31525782
- 11 + 31525771 = 31525782
- 19 + 31525763 = 31525782
- 59 + 31525723 = 31525782
- 83 + 31525699 = 31525782
- 131 + 31525651 = 31525782
- 173 + 31525609 = 31525782
- 179 + 31525603 = 31525782
Showing the first eight; more decompositions exist.
