Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515676, here are decompositions:

29 + 31515647 = 31515676
47 + 31515629 = 31515676
113 + 31515563 = 31515676
263 + 31515413 = 31515676
293 + 31515383 = 31515676
359 + 31515317 = 31515676
389 + 31515287 = 31515676
449 + 31515227 = 31515676

Showing the first eight; more decompositions exist.
