Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539054, here are decompositions:

7 + 31539047 = 31539054
11 + 31539043 = 31539054
47 + 31539007 = 31539054
67 + 31538987 = 31539054
103 + 31538951 = 31539054
167 + 31538887 = 31539054
227 + 31538827 = 31539054
311 + 31538743 = 31539054

Showing the first eight; more decompositions exist.
