Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535076, here are decompositions:

17 + 31535059 = 31535076
19 + 31535057 = 31535076
43 + 31535033 = 31535076
163 + 31534913 = 31535076
197 + 31534879 = 31535076
257 + 31534819 = 31535076
277 + 31534799 = 31535076
337 + 31534739 = 31535076

Showing the first eight; more decompositions exist.
