Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15430, here are decompositions:
- 3 + 15427 = 15430
- 17 + 15413 = 15430
- 29 + 15401 = 15430
- 47 + 15383 = 15430
- 53 + 15377 = 15430
- 71 + 15359 = 15430
- 101 + 15329 = 15430
- 131 + 15299 = 15430
Showing the first eight; more decompositions exist.
