Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493622, here are decompositions:

11 + 31493611 = 31493622
23 + 31493599 = 31493622
29 + 31493593 = 31493622
53 + 31493569 = 31493622
89 + 31493533 = 31493622
101 + 31493521 = 31493622
103 + 31493519 = 31493622
109 + 31493513 = 31493622

Showing the first eight; more decompositions exist.
