Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489996, here are decompositions:

47 + 31489949 = 31489996
53 + 31489943 = 31489996
113 + 31489883 = 31489996
179 + 31489817 = 31489996
383 + 31489613 = 31489996
563 + 31489433 = 31489996
569 + 31489427 = 31489996
647 + 31489349 = 31489996

Showing the first eight; more decompositions exist.
