Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535234, here are decompositions:

7 + 31535227 = 31535234
61 + 31535173 = 31535234
103 + 31535131 = 31535234
127 + 31535107 = 31535234
151 + 31535083 = 31535234
223 + 31535011 = 31535234
433 + 31534801 = 31535234
673 + 31534561 = 31535234

Showing the first eight; more decompositions exist.
