Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467776, here are decompositions:

13 + 31467763 = 31467776
409 + 31467367 = 31467776
547 + 31467229 = 31467776
577 + 31467199 = 31467776
607 + 31467169 = 31467776
619 + 31467157 = 31467776
643 + 31467133 = 31467776
673 + 31467103 = 31467776

Showing the first eight; more decompositions exist.
