Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529326, here are decompositions:

5 + 31529321 = 31529326
47 + 31529279 = 31529326
53 + 31529273 = 31529326
83 + 31529243 = 31529326
107 + 31529219 = 31529326
113 + 31529213 = 31529326
239 + 31529087 = 31529326
359 + 31528967 = 31529326

Showing the first eight; more decompositions exist.
