Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19662, here are decompositions:
- 53 + 19609 = 19662
- 59 + 19603 = 19662
- 79 + 19583 = 19662
- 103 + 19559 = 19662
- 109 + 19553 = 19662
- 131 + 19531 = 19662
- 173 + 19489 = 19662
- 179 + 19483 = 19662
Showing the first eight; more decompositions exist.
