Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478332, here are decompositions:

5 + 31478327 = 31478332
23 + 31478309 = 31478332
251 + 31478081 = 31478332
449 + 31477883 = 31478332
461 + 31477871 = 31478332
491 + 31477841 = 31478332
521 + 31477811 = 31478332
761 + 31477571 = 31478332

Showing the first eight; more decompositions exist.
