Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477564, here are decompositions:

3 + 31477561 = 31477564
11 + 31477553 = 31477564
137 + 31477427 = 31477564
263 + 31477301 = 31477564
383 + 31477181 = 31477564
401 + 31477163 = 31477564
617 + 31476947 = 31477564
647 + 31476917 = 31477564

Showing the first eight; more decompositions exist.
