Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19454, here are decompositions:
- 7 + 19447 = 19454
- 13 + 19441 = 19454
- 31 + 19423 = 19454
- 37 + 19417 = 19454
- 67 + 19387 = 19454
- 73 + 19381 = 19454
- 181 + 19273 = 19454
- 223 + 19231 = 19454
Showing the first eight; more decompositions exist.
