Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493714, here are decompositions:

3 + 31493711 = 31493714
37 + 31493677 = 31493714
61 + 31493653 = 31493714
73 + 31493641 = 31493714
103 + 31493611 = 31493714
157 + 31493557 = 31493714
181 + 31493533 = 31493714
193 + 31493521 = 31493714

Showing the first eight; more decompositions exist.
