Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178774, here are decompositions:
- 17 + 178757 = 178774
- 83 + 178691 = 178774
- 131 + 178643 = 178774
- 173 + 178601 = 178774
- 293 + 178481 = 178774
- 467 + 178307 = 178774
- 587 + 178187 = 178774
- 647 + 178127 = 178774
Showing the first eight; more decompositions exist.
