Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18394, here are decompositions:
- 23 + 18371 = 18394
- 41 + 18353 = 18394
- 53 + 18341 = 18394
- 83 + 18311 = 18394
- 107 + 18287 = 18394
- 137 + 18257 = 18394
- 251 + 18143 = 18394
- 263 + 18131 = 18394
Showing the first eight; more decompositions exist.
