Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88290, here are decompositions:

29 + 88261 = 88290
31 + 88259 = 88290
53 + 88237 = 88290
67 + 88223 = 88290
79 + 88211 = 88290
113 + 88177 = 88290
173 + 88117 = 88290
197 + 88093 = 88290

Showing the first eight; more decompositions exist.
