Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477270, here are decompositions:

89 + 31477181 = 31477270
107 + 31477163 = 31477270
191 + 31477079 = 31477270
311 + 31476959 = 31477270
353 + 31476917 = 31477270
389 + 31476881 = 31477270
449 + 31476821 = 31477270
647 + 31476623 = 31477270

Showing the first eight; more decompositions exist.
