Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18774, here are decompositions:
- 17 + 18757 = 18774
- 31 + 18743 = 18774
- 43 + 18731 = 18774
- 61 + 18713 = 18774
- 73 + 18701 = 18774
- 83 + 18691 = 18774
- 103 + 18671 = 18774
- 113 + 18661 = 18774
Showing the first eight; more decompositions exist.
