Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482140, here are decompositions:

37 + 31482103 = 31482140
43 + 31482097 = 31482140
73 + 31482067 = 31482140
97 + 31482043 = 31482140
103 + 31482037 = 31482140
127 + 31482013 = 31482140
229 + 31481911 = 31482140
241 + 31481899 = 31482140

Showing the first eight; more decompositions exist.
