Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517010, here are decompositions:

17 + 31516993 = 31517010
29 + 31516981 = 31517010
37 + 31516973 = 31517010
59 + 31516951 = 31517010
131 + 31516879 = 31517010
191 + 31516819 = 31517010
199 + 31516811 = 31517010
223 + 31516787 = 31517010

Showing the first eight; more decompositions exist.
