Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526768, here are decompositions:
- 19 + 31526749 = 31526768
- 37 + 31526731 = 31526768
- 79 + 31526689 = 31526768
- 151 + 31526617 = 31526768
- 241 + 31526527 = 31526768
- 271 + 31526497 = 31526768
- 337 + 31526431 = 31526768
- 349 + 31526419 = 31526768
Showing the first eight; more decompositions exist.
