Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555014, here are decompositions:

53 + 31554961 = 31555014
67 + 31554947 = 31555014
131 + 31554883 = 31555014
151 + 31554863 = 31555014
163 + 31554851 = 31555014
173 + 31554841 = 31555014
191 + 31554823 = 31555014
223 + 31554791 = 31555014

Showing the first eight; more decompositions exist.
