Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529686, here are decompositions:

5 + 31529681 = 31529686
17 + 31529669 = 31529686
179 + 31529507 = 31529686
239 + 31529447 = 31529686
443 + 31529243 = 31529686
467 + 31529219 = 31529686
599 + 31529087 = 31529686
719 + 31528967 = 31529686

Showing the first eight; more decompositions exist.
