Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476838, here are decompositions:

17 + 31476821 = 31476838
227 + 31476611 = 31476838
251 + 31476587 = 31476838
389 + 31476449 = 31476838
401 + 31476437 = 31476838
467 + 31476371 = 31476838
521 + 31476317 = 31476838
587 + 31476251 = 31476838

Showing the first eight; more decompositions exist.
