Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493766, here are decompositions:

23 + 31493743 = 31493766
89 + 31493677 = 31493766
113 + 31493653 = 31493766
167 + 31493599 = 31493766
173 + 31493593 = 31493766
193 + 31493573 = 31493766
197 + 31493569 = 31493766
233 + 31493533 = 31493766

Showing the first eight; more decompositions exist.
