Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517046, here are decompositions:

7 + 31517039 = 31517046
19 + 31517027 = 31517046
53 + 31516993 = 31517046
73 + 31516973 = 31517046
157 + 31516889 = 31517046
167 + 31516879 = 31517046
227 + 31516819 = 31517046
257 + 31516789 = 31517046

Showing the first eight; more decompositions exist.
