Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517050, here are decompositions:

11 + 31517039 = 31517050
23 + 31517027 = 31517050
29 + 31517021 = 31517050
239 + 31516811 = 31517050
263 + 31516787 = 31517050
269 + 31516781 = 31517050
293 + 31516757 = 31517050
347 + 31516703 = 31517050

Showing the first eight; more decompositions exist.
