Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18732, here are decompositions:

13 + 18719 = 18732
19 + 18713 = 18732
31 + 18701 = 18732
41 + 18691 = 18732
53 + 18679 = 18732
61 + 18671 = 18732
71 + 18661 = 18732
139 + 18593 = 18732

Showing the first eight; more decompositions exist.
