Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535326, here are decompositions:

5 + 31535321 = 31535326
107 + 31535219 = 31535326
113 + 31535213 = 31535326
269 + 31535057 = 31535326
293 + 31535033 = 31535326
569 + 31534757 = 31535326
587 + 31534739 = 31535326
617 + 31534709 = 31535326

Showing the first eight; more decompositions exist.
