Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467788, here are decompositions:

61 + 31467727 = 31467788
67 + 31467721 = 31467788
97 + 31467691 = 31467788
199 + 31467589 = 31467788
229 + 31467559 = 31467788
307 + 31467481 = 31467788
421 + 31467367 = 31467788
487 + 31467301 = 31467788

Showing the first eight; more decompositions exist.
