Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485496, here are decompositions:

23 + 31485473 = 31485496
47 + 31485449 = 31485496
89 + 31485407 = 31485496
113 + 31485383 = 31485496
137 + 31485359 = 31485496
227 + 31485269 = 31485496
389 + 31485107 = 31485496
479 + 31485017 = 31485496

Showing the first eight; more decompositions exist.
