Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42626, here are decompositions:
- 37 + 42589 = 42626
- 127 + 42499 = 42626
- 139 + 42487 = 42626
- 163 + 42463 = 42626
- 193 + 42433 = 42626
- 223 + 42403 = 42626
- 229 + 42397 = 42626
- 277 + 42349 = 42626
Showing the first eight; more decompositions exist.
