Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485362, here are decompositions:

3 + 31485359 = 31485362
43 + 31485319 = 31485362
61 + 31485301 = 31485362
79 + 31485283 = 31485362
241 + 31485121 = 31485362
283 + 31485079 = 31485362
313 + 31485049 = 31485362
331 + 31485031 = 31485362

Showing the first eight; more decompositions exist.
