Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515634, here are decompositions:

5 + 31515629 = 31515634
23 + 31515611 = 31515634
71 + 31515563 = 31515634
233 + 31515401 = 31515634
251 + 31515383 = 31515634
257 + 31515377 = 31515634
281 + 31515353 = 31515634
317 + 31515317 = 31515634

Showing the first eight; more decompositions exist.
