Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42722, here are decompositions:
- 3 + 42719 = 42722
- 13 + 42709 = 42722
- 19 + 42703 = 42722
- 73 + 42649 = 42722
- 79 + 42643 = 42722
- 151 + 42571 = 42722
- 223 + 42499 = 42722
- 271 + 42451 = 42722
Showing the first eight; more decompositions exist.
