Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31578714, here are decompositions:

17 + 31578697 = 31578714
23 + 31578691 = 31578714
103 + 31578611 = 31578714
107 + 31578607 = 31578714
113 + 31578601 = 31578714
131 + 31578583 = 31578714
137 + 31578577 = 31578714
157 + 31578557 = 31578714

Showing the first eight; more decompositions exist.
