Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19386, here are decompositions:
- 5 + 19381 = 19386
- 7 + 19379 = 19386
- 13 + 19373 = 19386
- 53 + 19333 = 19386
- 67 + 19319 = 19386
- 97 + 19289 = 19386
- 113 + 19273 = 19386
- 127 + 19259 = 19386
Showing the first eight; more decompositions exist.
