Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517102, here are decompositions:

109 + 31516993 = 31517102
151 + 31516951 = 31517102
223 + 31516879 = 31517102
283 + 31516819 = 31517102
313 + 31516789 = 31517102
349 + 31516753 = 31517102
373 + 31516729 = 31517102
433 + 31516669 = 31517102

Showing the first eight; more decompositions exist.
