Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18750, here are decompositions:

7 + 18743 = 18750
19 + 18731 = 18750
31 + 18719 = 18750
37 + 18713 = 18750
59 + 18691 = 18750
71 + 18679 = 18750
79 + 18671 = 18750
89 + 18661 = 18750

Showing the first eight; more decompositions exist.
