Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84772, here are decompositions:

11 + 84761 = 84772
41 + 84731 = 84772
53 + 84719 = 84772
59 + 84713 = 84772
71 + 84701 = 84772
113 + 84659 = 84772
239 + 84533 = 84772
251 + 84521 = 84772

Showing the first eight; more decompositions exist.
