Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18850, here are decompositions:

11 + 18839 = 18850
47 + 18803 = 18850
53 + 18797 = 18850
101 + 18749 = 18850
107 + 18743 = 18850
131 + 18719 = 18850
137 + 18713 = 18850
149 + 18701 = 18850

Showing the first eight; more decompositions exist.
