Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477504, here are decompositions:

557 + 31476947 = 31477504
587 + 31476917 = 31477504
683 + 31476821 = 31477504
761 + 31476743 = 31477504
881 + 31476623 = 31477504
911 + 31476593 = 31477504
953 + 31476551 = 31477504
1091 + 31476413 = 31477504

Showing the first eight; more decompositions exist.
