Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18956, here are decompositions:

37 + 18919 = 18956
43 + 18913 = 18956
97 + 18859 = 18956
163 + 18793 = 18956
199 + 18757 = 18956
277 + 18679 = 18956
373 + 18583 = 18956
433 + 18523 = 18956

Showing the first eight; more decompositions exist.
