Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476868, here are decompositions:

47 + 31476821 = 31476868
257 + 31476611 = 31476868
281 + 31476587 = 31476868
317 + 31476551 = 31476868
359 + 31476509 = 31476868
419 + 31476449 = 31476868
431 + 31476437 = 31476868
617 + 31476251 = 31476868

Showing the first eight; more decompositions exist.
