Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545548, here are decompositions:
- 61 + 31545487 = 31545548
- 79 + 31545469 = 31545548
- 109 + 31545439 = 31545548
- 157 + 31545391 = 31545548
- 337 + 31545211 = 31545548
- 367 + 31545181 = 31545548
- 457 + 31545091 = 31545548
- 487 + 31545061 = 31545548
Showing the first eight; more decompositions exist.
