Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19514, here are decompositions:
- 7 + 19507 = 19514
- 13 + 19501 = 19514
- 31 + 19483 = 19514
- 37 + 19477 = 19514
- 43 + 19471 = 19514
- 67 + 19447 = 19514
- 73 + 19441 = 19514
- 97 + 19417 = 19514
Showing the first eight; more decompositions exist.
