Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16394, here are decompositions:
- 13 + 16381 = 16394
- 31 + 16363 = 16394
- 61 + 16333 = 16394
- 127 + 16267 = 16394
- 163 + 16231 = 16394
- 211 + 16183 = 16394
- 283 + 16111 = 16394
- 307 + 16087 = 16394
Showing the first eight; more decompositions exist.
