Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40788, here are decompositions:
- 17 + 40771 = 40788
- 29 + 40759 = 40788
- 37 + 40751 = 40788
- 79 + 40709 = 40788
- 89 + 40699 = 40788
- 149 + 40639 = 40788
- 151 + 40637 = 40788
- 179 + 40609 = 40788
Showing the first eight; more decompositions exist.
