Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526748, here are decompositions:
- 17 + 31526731 = 31526748
- 59 + 31526689 = 31526748
- 79 + 31526669 = 31526748
- 101 + 31526647 = 31526748
- 131 + 31526617 = 31526748
- 251 + 31526497 = 31526748
- 271 + 31526477 = 31526748
- 317 + 31526431 = 31526748
Showing the first eight; more decompositions exist.
