Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493610, here are decompositions:

11 + 31493599 = 31493610
17 + 31493593 = 31493610
37 + 31493573 = 31493610
41 + 31493569 = 31493610
53 + 31493557 = 31493610
89 + 31493521 = 31493610
97 + 31493513 = 31493610
163 + 31493447 = 31493610

Showing the first eight; more decompositions exist.
