Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529458, here are decompositions:

11 + 31529447 = 31529458
137 + 31529321 = 31529458
179 + 31529279 = 31529458
239 + 31529219 = 31529458
461 + 31528997 = 31529458
491 + 31528967 = 31529458
617 + 31528841 = 31529458
647 + 31528811 = 31529458

Showing the first eight; more decompositions exist.
