Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532718, here are decompositions:

31 + 31532687 = 31532718
59 + 31532659 = 31532718
79 + 31532639 = 31532718
131 + 31532587 = 31532718
137 + 31532581 = 31532718
167 + 31532551 = 31532718
179 + 31532539 = 31532718
197 + 31532521 = 31532718

Showing the first eight; more decompositions exist.
