Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526788, here are decompositions:
- 11 + 31526777 = 31526788
- 17 + 31526771 = 31526788
- 311 + 31526477 = 31526788
- 401 + 31526387 = 31526788
- 599 + 31526189 = 31526788
- 647 + 31526141 = 31526788
- 701 + 31526087 = 31526788
- 719 + 31526069 = 31526788
Showing the first eight; more decompositions exist.
