Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86922, here are decompositions:

53 + 86869 = 86922
61 + 86861 = 86922
71 + 86851 = 86922
79 + 86843 = 86922
109 + 86813 = 86922
139 + 86783 = 86922
151 + 86771 = 86922
179 + 86743 = 86922

Showing the first eight; more decompositions exist.
