Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518714, here are decompositions:

23 + 31518691 = 31518714
37 + 31518677 = 31518714
41 + 31518673 = 31518714
61 + 31518653 = 31518714
67 + 31518647 = 31518714
107 + 31518607 = 31518714
113 + 31518601 = 31518714
173 + 31518541 = 31518714

Showing the first eight; more decompositions exist.
