Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535102, here are decompositions:

19 + 31535083 = 31535102
43 + 31535059 = 31535102
103 + 31534999 = 31535102
223 + 31534879 = 31535102
229 + 31534873 = 31535102
271 + 31534831 = 31535102
283 + 31534819 = 31535102
349 + 31534753 = 31535102

Showing the first eight; more decompositions exist.
