Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477076, here are decompositions:

13 + 31477063 = 31477076
19 + 31477057 = 31477076
223 + 31476853 = 31477076
229 + 31476847 = 31477076
277 + 31476799 = 31477076
349 + 31476727 = 31477076
373 + 31476703 = 31477076
577 + 31476499 = 31477076

Showing the first eight; more decompositions exist.
