Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525844, here are decompositions:
- 3 + 31525841 = 31525844
- 61 + 31525783 = 31525844
- 67 + 31525777 = 31525844
- 73 + 31525771 = 31525844
- 127 + 31525717 = 31525844
- 157 + 31525687 = 31525844
- 193 + 31525651 = 31525844
- 241 + 31525603 = 31525844
Showing the first eight; more decompositions exist.
