Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565062, here are decompositions:

5 + 31565057 = 31565062
71 + 31564991 = 31565062
83 + 31564979 = 31565062
281 + 31564781 = 31565062
293 + 31564769 = 31565062
401 + 31564661 = 31565062
449 + 31564613 = 31565062
701 + 31564361 = 31565062

Showing the first eight; more decompositions exist.
