Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477126, here are decompositions:

47 + 31477079 = 31477126
59 + 31477067 = 31477126
167 + 31476959 = 31477126
179 + 31476947 = 31477126
383 + 31476743 = 31477126
503 + 31476623 = 31477126
617 + 31476509 = 31477126
677 + 31476449 = 31477126

Showing the first eight; more decompositions exist.
