Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464814, here are decompositions:

5 + 31464809 = 31464814
83 + 31464731 = 31464814
113 + 31464701 = 31464814
197 + 31464617 = 31464814
233 + 31464581 = 31464814
257 + 31464557 = 31464814
677 + 31464137 = 31464814
971 + 31463843 = 31464814

Showing the first eight; more decompositions exist.
