Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475884, here are decompositions:

71 + 31475813 = 31475884
107 + 31475777 = 31475884
113 + 31475771 = 31475884
431 + 31475453 = 31475884
491 + 31475393 = 31475884
563 + 31475321 = 31475884
641 + 31475243 = 31475884
653 + 31475231 = 31475884

Showing the first eight; more decompositions exist.
