Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525874, here are decompositions:
- 97 + 31525777 = 31525874
- 103 + 31525771 = 31525874
- 151 + 31525723 = 31525874
- 157 + 31525717 = 31525874
- 223 + 31525651 = 31525874
- 271 + 31525603 = 31525874
- 307 + 31525567 = 31525874
- 337 + 31525537 = 31525874
Showing the first eight; more decompositions exist.
