Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535082, here are decompositions:

23 + 31535059 = 31535082
71 + 31535011 = 31535082
83 + 31534999 = 31535082
101 + 31534981 = 31535082
211 + 31534871 = 31535082
251 + 31534831 = 31535082
263 + 31534819 = 31535082
281 + 31534801 = 31535082

Showing the first eight; more decompositions exist.
