Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526778, here are decompositions:
- 5 + 31526773 = 31526778
- 7 + 31526771 = 31526778
- 29 + 31526749 = 31526778
- 47 + 31526731 = 31526778
- 89 + 31526689 = 31526778
- 109 + 31526669 = 31526778
- 131 + 31526647 = 31526778
- 251 + 31526527 = 31526778
Showing the first eight; more decompositions exist.
