Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477234, here are decompositions:

53 + 31477181 = 31477234
71 + 31477163 = 31477234
167 + 31477067 = 31477234
317 + 31476917 = 31477234
353 + 31476881 = 31477234
491 + 31476743 = 31477234
641 + 31476593 = 31477234
647 + 31476587 = 31477234

Showing the first eight; more decompositions exist.
