Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476874, here are decompositions:

3 + 31476871 = 31476874
53 + 31476821 = 31476874
131 + 31476743 = 31476874
251 + 31476623 = 31476874
263 + 31476611 = 31476874
281 + 31476593 = 31476874
461 + 31476413 = 31476874
491 + 31476383 = 31476874

Showing the first eight; more decompositions exist.
