Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532614, here are decompositions:

17 + 31532597 = 31532614
41 + 31532573 = 31532614
107 + 31532507 = 31532614
137 + 31532477 = 31532614
353 + 31532261 = 31532614
593 + 31532021 = 31532614
647 + 31531967 = 31532614
683 + 31531931 = 31532614

Showing the first eight; more decompositions exist.
