Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478324, here are decompositions:

37 + 31478287 = 31478324
151 + 31478173 = 31478324
307 + 31478017 = 31478324
331 + 31477993 = 31478324
373 + 31477951 = 31478324
571 + 31477753 = 31478324
601 + 31477723 = 31478324
607 + 31477717 = 31478324

Showing the first eight; more decompositions exist.
