Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517058, here are decompositions:

19 + 31517039 = 31517058
31 + 31517027 = 31517058
37 + 31517021 = 31517058
47 + 31517011 = 31517058
107 + 31516951 = 31517058
179 + 31516879 = 31517058
239 + 31516819 = 31517058
269 + 31516789 = 31517058

Showing the first eight; more decompositions exist.
