Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529586, here are decompositions:

19 + 31529567 = 31529586
29 + 31529557 = 31529586
47 + 31529539 = 31529586
79 + 31529507 = 31529586
107 + 31529479 = 31529586
139 + 31529447 = 31529586
173 + 31529413 = 31529586
227 + 31529359 = 31529586

Showing the first eight; more decompositions exist.
