Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517196, here are decompositions:

47 + 31517149 = 31517196
157 + 31517039 = 31517196
223 + 31516973 = 31517196
307 + 31516889 = 31517196
317 + 31516879 = 31517196
409 + 31516787 = 31517196
419 + 31516777 = 31517196
439 + 31516757 = 31517196

Showing the first eight; more decompositions exist.
