Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565034, here are decompositions:

5 + 31565029 = 31565034
43 + 31564991 = 31565034
101 + 31564933 = 31565034
107 + 31564927 = 31565034
113 + 31564921 = 31565034
181 + 31564853 = 31565034
227 + 31564807 = 31565034
311 + 31564723 = 31565034

Showing the first eight; more decompositions exist.
