Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529134, here are decompositions:

47 + 31529087 = 31529134
53 + 31529081 = 31529134
137 + 31528997 = 31529134
167 + 31528967 = 31529134
281 + 31528853 = 31529134
293 + 31528841 = 31529134
311 + 31528823 = 31529134
383 + 31528751 = 31529134

Showing the first eight; more decompositions exist.
