Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535008, here are decompositions:

47 + 31534961 = 31535008
137 + 31534871 = 31535008
251 + 31534757 = 31535008
257 + 31534751 = 31535008
269 + 31534739 = 31535008
317 + 31534691 = 31535008
419 + 31534589 = 31535008
521 + 31534487 = 31535008

Showing the first eight; more decompositions exist.
