Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84172, here are decompositions:

29 + 84143 = 84172
41 + 84131 = 84172
83 + 84089 = 84172
113 + 84059 = 84172
233 + 83939 = 84172
239 + 83933 = 84172
251 + 83921 = 84172
269 + 83903 = 84172

Showing the first eight; more decompositions exist.
