Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535124, here are decompositions:

11 + 31535113 = 31535124
17 + 31535107 = 31535124
41 + 31535083 = 31535124
43 + 31535081 = 31535124
67 + 31535057 = 31535124
113 + 31535011 = 31535124
163 + 31534961 = 31535124
211 + 31534913 = 31535124

Showing the first eight; more decompositions exist.
