Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18612, here are decompositions:
- 19 + 18593 = 18612
- 29 + 18583 = 18612
- 59 + 18553 = 18612
- 71 + 18541 = 18612
- 73 + 18539 = 18612
- 89 + 18523 = 18612
- 109 + 18503 = 18612
- 131 + 18481 = 18612
Showing the first eight; more decompositions exist.
