Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477348, here are decompositions:

47 + 31477301 = 31477348
59 + 31477289 = 31477348
167 + 31477181 = 31477348
269 + 31477079 = 31477348
281 + 31477067 = 31477348
389 + 31476959 = 31477348
401 + 31476947 = 31477348
431 + 31476917 = 31477348

Showing the first eight; more decompositions exist.
