Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529386, here are decompositions:

107 + 31529279 = 31529386
113 + 31529273 = 31529386
137 + 31529249 = 31529386
167 + 31529219 = 31529386
173 + 31529213 = 31529386
389 + 31528997 = 31529386
419 + 31528967 = 31529386
563 + 31528823 = 31529386

Showing the first eight; more decompositions exist.
