Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99540, here are decompositions:
- 11 + 99529 = 99540
- 13 + 99527 = 99540
- 17 + 99523 = 99540
- 43 + 99497 = 99540
- 53 + 99487 = 99540
- 71 + 99469 = 99540
- 101 + 99439 = 99540
- 109 + 99431 = 99540
Showing the first eight; more decompositions exist.
