Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565092, here are decompositions:

5 + 31565087 = 31565092
23 + 31565069 = 31565092
101 + 31564991 = 31565092
113 + 31564979 = 31565092
149 + 31564943 = 31565092
173 + 31564919 = 31565092
239 + 31564853 = 31565092
311 + 31564781 = 31565092

Showing the first eight; more decompositions exist.
