Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517112, here are decompositions:

73 + 31517039 = 31517112
101 + 31517011 = 31517112
131 + 31516981 = 31517112
139 + 31516973 = 31517112
223 + 31516889 = 31517112
233 + 31516879 = 31517112
271 + 31516841 = 31517112
293 + 31516819 = 31517112

Showing the first eight; more decompositions exist.
