Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529226, here are decompositions:

7 + 31529219 = 31529226
13 + 31529213 = 31529226
59 + 31529167 = 31529226
137 + 31529089 = 31529226
139 + 31529087 = 31529226
173 + 31529053 = 31529226
229 + 31528997 = 31529226
233 + 31528993 = 31529226

Showing the first eight; more decompositions exist.
