Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566702, here are decompositions:

43 + 31566659 = 31566702
71 + 31566631 = 31566702
103 + 31566599 = 31566702
113 + 31566589 = 31566702
179 + 31566523 = 31566702
229 + 31566473 = 31566702
313 + 31566389 = 31566702
353 + 31566349 = 31566702

Showing the first eight; more decompositions exist.
