Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477498, here are decompositions:

71 + 31477427 = 31477498
149 + 31477349 = 31477498
197 + 31477301 = 31477498
317 + 31477181 = 31477498
419 + 31477079 = 31477498
431 + 31477067 = 31477498
617 + 31476881 = 31477498
677 + 31476821 = 31477498

Showing the first eight; more decompositions exist.
