Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478696, here are decompositions:

97 + 31478599 = 31478696
103 + 31478593 = 31478696
307 + 31478389 = 31478696
373 + 31478323 = 31478696
409 + 31478287 = 31478696
523 + 31478173 = 31478696
607 + 31478089 = 31478696
619 + 31478077 = 31478696

Showing the first eight; more decompositions exist.
