Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476958, here are decompositions:

11 + 31476947 = 31476958
41 + 31476917 = 31476958
137 + 31476821 = 31476958
347 + 31476611 = 31476958
449 + 31476509 = 31476958
509 + 31476449 = 31476958
521 + 31476437 = 31476958
587 + 31476371 = 31476958

Showing the first eight; more decompositions exist.
