Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178794, here are decompositions:
- 13 + 178781 = 178794
- 37 + 178757 = 178794
- 41 + 178753 = 178794
- 97 + 178697 = 178794
- 101 + 178693 = 178794
- 103 + 178691 = 178794
- 113 + 178681 = 178794
- 151 + 178643 = 178794
Showing the first eight; more decompositions exist.
