Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529614, here are decompositions:

47 + 31529567 = 31529614
107 + 31529507 = 31529614
167 + 31529447 = 31529614
293 + 31529321 = 31529614
401 + 31529213 = 31529614
617 + 31528997 = 31529614
647 + 31528967 = 31529614
761 + 31528853 = 31529614

Showing the first eight; more decompositions exist.
