Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478996, here are decompositions:

13 + 31478983 = 31478996
37 + 31478959 = 31478996
277 + 31478719 = 31478996
349 + 31478647 = 31478996
397 + 31478599 = 31478996
607 + 31478389 = 31478996
673 + 31478323 = 31478996
709 + 31478287 = 31478996

Showing the first eight; more decompositions exist.
