Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534918, here are decompositions:

5 + 31534913 = 31534918
47 + 31534871 = 31534918
131 + 31534787 = 31534918
167 + 31534751 = 31534918
179 + 31534739 = 31534918
227 + 31534691 = 31534918
281 + 31534637 = 31534918
431 + 31534487 = 31534918

Showing the first eight; more decompositions exist.
