Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493634, here are decompositions:

23 + 31493611 = 31493634
41 + 31493593 = 31493634
61 + 31493573 = 31493634
101 + 31493533 = 31493634
113 + 31493521 = 31493634
157 + 31493477 = 31493634
167 + 31493467 = 31493634
191 + 31493443 = 31493634

Showing the first eight; more decompositions exist.
