Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529878, here are decompositions:

59 + 31529819 = 31529878
197 + 31529681 = 31529878
227 + 31529651 = 31529878
311 + 31529567 = 31529878
431 + 31529447 = 31529878
557 + 31529321 = 31529878
599 + 31529279 = 31529878
659 + 31529219 = 31529878

Showing the first eight; more decompositions exist.
