Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485462, here are decompositions:

13 + 31485449 = 31485462
31 + 31485431 = 31485462
61 + 31485401 = 31485462
79 + 31485383 = 31485462
83 + 31485379 = 31485462
103 + 31485359 = 31485462
109 + 31485353 = 31485462
149 + 31485313 = 31485462

Showing the first eight; more decompositions exist.
