Goldbach decomposition

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.
