Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493726, here are decompositions:

37 + 31493689 = 31493726
73 + 31493653 = 31493726
127 + 31493599 = 31493726
157 + 31493569 = 31493726
193 + 31493533 = 31493726
283 + 31493443 = 31493726
307 + 31493419 = 31493726
349 + 31493377 = 31493726

Showing the first eight; more decompositions exist.
