Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525568, here are decompositions:
- 31 + 31525537 = 31525568
- 79 + 31525489 = 31525568
- 307 + 31525261 = 31525568
- 367 + 31525201 = 31525568
- 541 + 31525027 = 31525568
- 577 + 31524991 = 31525568
- 601 + 31524967 = 31525568
- 631 + 31524937 = 31525568
Showing the first eight; more decompositions exist.
