Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561134, here are decompositions:

13 + 31561121 = 31561134
41 + 31561093 = 31561134
67 + 31561067 = 31561134
131 + 31561003 = 31561134
151 + 31560983 = 31561134
191 + 31560943 = 31561134
193 + 31560941 = 31561134
223 + 31560911 = 31561134

Showing the first eight; more decompositions exist.
