Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565032, here are decompositions:

3 + 31565029 = 31565032
41 + 31564991 = 31565032
53 + 31564979 = 31565032
89 + 31564943 = 31565032
113 + 31564919 = 31565032
179 + 31564853 = 31565032
251 + 31564781 = 31565032
263 + 31564769 = 31565032

Showing the first eight; more decompositions exist.
