Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39642, here are decompositions:
- 11 + 39631 = 39642
- 19 + 39623 = 39642
- 23 + 39619 = 39642
- 61 + 39581 = 39642
- 73 + 39569 = 39642
- 79 + 39563 = 39642
- 101 + 39541 = 39642
- 131 + 39511 = 39642
Showing the first eight; more decompositions exist.
