Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470328, here are decompositions:

5 + 31470323 = 31470328
107 + 31470221 = 31470328
467 + 31469861 = 31470328
479 + 31469849 = 31470328
587 + 31469741 = 31470328
797 + 31469531 = 31470328
809 + 31469519 = 31470328
881 + 31469447 = 31470328

Showing the first eight; more decompositions exist.
