Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525760, here are decompositions:
- 37 + 31525723 = 31525760
- 43 + 31525717 = 31525760
- 61 + 31525699 = 31525760
- 73 + 31525687 = 31525760
- 103 + 31525657 = 31525760
- 109 + 31525651 = 31525760
- 151 + 31525609 = 31525760
- 157 + 31525603 = 31525760
Showing the first eight; more decompositions exist.
