Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485616, here are decompositions:

5 + 31485611 = 31485616
17 + 31485599 = 31485616
83 + 31485533 = 31485616
167 + 31485449 = 31485616
233 + 31485383 = 31485616
257 + 31485359 = 31485616
263 + 31485353 = 31485616
347 + 31485269 = 31485616

Showing the first eight; more decompositions exist.
