Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467944, here are decompositions:

7 + 31467937 = 31467944
97 + 31467847 = 31467944
181 + 31467763 = 31467944
223 + 31467721 = 31467944
373 + 31467571 = 31467944
463 + 31467481 = 31467944
577 + 31467367 = 31467944
643 + 31467301 = 31467944

Showing the first eight; more decompositions exist.
