Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477468, here are decompositions:

41 + 31477427 = 31477468
89 + 31477379 = 31477468
167 + 31477301 = 31477468
179 + 31477289 = 31477468
389 + 31477079 = 31477468
401 + 31477067 = 31477468
509 + 31476959 = 31477468
521 + 31476947 = 31477468

Showing the first eight; more decompositions exist.
