Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87722, here are decompositions:
- 3 + 87719 = 87722
- 31 + 87691 = 87722
- 43 + 87679 = 87722
- 73 + 87649 = 87722
- 79 + 87643 = 87722
- 109 + 87613 = 87722
- 139 + 87583 = 87722
- 163 + 87559 = 87722
Showing the first eight; more decompositions exist.
