Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535118, here are decompositions:

5 + 31535113 = 31535118
11 + 31535107 = 31535118
37 + 31535081 = 31535118
59 + 31535059 = 31535118
61 + 31535057 = 31535118
107 + 31535011 = 31535118
137 + 31534981 = 31535118
157 + 31534961 = 31535118

Showing the first eight; more decompositions exist.
