Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535050, here are decompositions:

17 + 31535033 = 31535050
89 + 31534961 = 31535050
137 + 31534913 = 31535050
179 + 31534871 = 31535050
251 + 31534799 = 31535050
263 + 31534787 = 31535050
293 + 31534757 = 31535050
311 + 31534739 = 31535050

Showing the first eight; more decompositions exist.
