Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482894, here are decompositions:

5 + 31482889 = 31482894
61 + 31482833 = 31482894
71 + 31482823 = 31482894
73 + 31482821 = 31482894
151 + 31482743 = 31482894
211 + 31482683 = 31482894
227 + 31482667 = 31482894
251 + 31482643 = 31482894

Showing the first eight; more decompositions exist.
