Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525740, here are decompositions:
- 17 + 31525723 = 31525740
- 23 + 31525717 = 31525740
- 41 + 31525699 = 31525740
- 53 + 31525687 = 31525740
- 83 + 31525657 = 31525740
- 89 + 31525651 = 31525740
- 131 + 31525609 = 31525740
- 137 + 31525603 = 31525740
Showing the first eight; more decompositions exist.
