Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88390, here are decompositions:

11 + 88379 = 88390
53 + 88337 = 88390
89 + 88301 = 88390
101 + 88289 = 88390
131 + 88259 = 88390
149 + 88241 = 88390
167 + 88223 = 88390
179 + 88211 = 88390

Showing the first eight; more decompositions exist.
