Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65642, here are decompositions:
- 13 + 65629 = 65642
- 43 + 65599 = 65642
- 61 + 65581 = 65642
- 79 + 65563 = 65642
- 103 + 65539 = 65642
- 163 + 65479 = 65642
- 193 + 65449 = 65642
- 223 + 65419 = 65642
Showing the first eight; more decompositions exist.
