Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23642, here are decompositions:
- 13 + 23629 = 23642
- 19 + 23623 = 23642
- 43 + 23599 = 23642
- 61 + 23581 = 23642
- 79 + 23563 = 23642
- 103 + 23539 = 23642
- 211 + 23431 = 23642
- 271 + 23371 = 23642
Showing the first eight; more decompositions exist.
