Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566734, here are decompositions:

103 + 31566631 = 31566734
193 + 31566541 = 31566734
211 + 31566523 = 31566734
307 + 31566427 = 31566734
337 + 31566397 = 31566734
487 + 31566247 = 31566734
673 + 31566061 = 31566734
691 + 31566043 = 31566734

Showing the first eight; more decompositions exist.
