Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579014, here are decompositions:

11 + 31579003 = 31579014
41 + 31578973 = 31579014
67 + 31578947 = 31579014
127 + 31578887 = 31579014
193 + 31578821 = 31579014
223 + 31578791 = 31579014
227 + 31578787 = 31579014
251 + 31578763 = 31579014

Showing the first eight; more decompositions exist.
