Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478348, here are decompositions:

7 + 31478341 = 31478348
61 + 31478287 = 31478348
271 + 31478077 = 31478348
331 + 31478017 = 31478348
379 + 31477969 = 31478348
397 + 31477951 = 31478348
619 + 31477729 = 31478348
631 + 31477717 = 31478348

Showing the first eight; more decompositions exist.
