Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482090, here are decompositions:

7 + 31482083 = 31482090
23 + 31482067 = 31482090
43 + 31482047 = 31482090
47 + 31482043 = 31482090
53 + 31482037 = 31482090
109 + 31481981 = 31482090
139 + 31481951 = 31482090
151 + 31481939 = 31482090

Showing the first eight; more decompositions exist.
