Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493076, here are decompositions:

7 + 31493069 = 31493076
19 + 31493057 = 31493076
23 + 31493053 = 31493076
29 + 31493047 = 31493076
37 + 31493039 = 31493076
47 + 31493029 = 31493076
59 + 31493017 = 31493076
67 + 31493009 = 31493076

Showing the first eight; more decompositions exist.
