Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493762, here are decompositions:

19 + 31493743 = 31493762
73 + 31493689 = 31493762
109 + 31493653 = 31493762
151 + 31493611 = 31493762
163 + 31493599 = 31493762
193 + 31493569 = 31493762
229 + 31493533 = 31493762
241 + 31493521 = 31493762

Showing the first eight; more decompositions exist.
