Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535112, here are decompositions:

5 + 31535107 = 31535112
29 + 31535083 = 31535112
31 + 31535081 = 31535112
53 + 31535059 = 31535112
79 + 31535033 = 31535112
101 + 31535011 = 31535112
113 + 31534999 = 31535112
131 + 31534981 = 31535112

Showing the first eight; more decompositions exist.
