Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477048, here are decompositions:

89 + 31476959 = 31477048
101 + 31476947 = 31477048
131 + 31476917 = 31477048
167 + 31476881 = 31477048
227 + 31476821 = 31477048
461 + 31476587 = 31477048
587 + 31476461 = 31477048
599 + 31476449 = 31477048

Showing the first eight; more decompositions exist.
