Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19590, here are decompositions:
- 7 + 19583 = 19590
- 13 + 19577 = 19590
- 19 + 19571 = 19590
- 31 + 19559 = 19590
- 37 + 19553 = 19590
- 47 + 19543 = 19590
- 59 + 19531 = 19590
- 83 + 19507 = 19590
Showing the first eight; more decompositions exist.
