Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18600, here are decompositions:
- 7 + 18593 = 18600
- 13 + 18587 = 18600
- 17 + 18583 = 18600
- 47 + 18553 = 18600
- 59 + 18541 = 18600
- 61 + 18539 = 18600
- 79 + 18521 = 18600
- 83 + 18517 = 18600
Showing the first eight; more decompositions exist.
