Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115290, here are decompositions:

11 + 115279 = 115290
31 + 115259 = 115290
41 + 115249 = 115290
53 + 115237 = 115290
67 + 115223 = 115290
79 + 115211 = 115290
89 + 115201 = 115290
107 + 115183 = 115290

Showing the first eight; more decompositions exist.
