Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534090, here are decompositions:

11 + 31534079 = 31534090
17 + 31534073 = 31534090
23 + 31534067 = 31534090
131 + 31533959 = 31534090
167 + 31533923 = 31534090
179 + 31533911 = 31534090
251 + 31533839 = 31534090
257 + 31533833 = 31534090

Showing the first eight; more decompositions exist.
