Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485682, here are decompositions:

29 + 31485653 = 31485682
71 + 31485611 = 31485682
83 + 31485599 = 31485682
149 + 31485533 = 31485682
233 + 31485449 = 31485682
251 + 31485431 = 31485682
281 + 31485401 = 31485682
461 + 31485221 = 31485682

Showing the first eight; more decompositions exist.
