Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461064, here are decompositions:

17 + 31461047 = 31461064
53 + 31461011 = 31461064
113 + 31460951 = 31461064
137 + 31460927 = 31461064
191 + 31460873 = 31461064
227 + 31460837 = 31461064
233 + 31460831 = 31461064
281 + 31460783 = 31461064

Showing the first eight; more decompositions exist.
