Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515796, here are decompositions:

29 + 31515767 = 31515796
113 + 31515683 = 31515796
149 + 31515647 = 31515796
167 + 31515629 = 31515796
197 + 31515599 = 31515796
233 + 31515563 = 31515796
239 + 31515557 = 31515796
383 + 31515413 = 31515796

Showing the first eight; more decompositions exist.
