Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493062, here are decompositions:

5 + 31493057 = 31493062
23 + 31493039 = 31493062
53 + 31493009 = 31493062
71 + 31492991 = 31493062
281 + 31492781 = 31493062
311 + 31492751 = 31493062
509 + 31492553 = 31493062
521 + 31492541 = 31493062

Showing the first eight; more decompositions exist.
