Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535068, here are decompositions:

11 + 31535057 = 31535068
107 + 31534961 = 31535068
197 + 31534871 = 31535068
269 + 31534799 = 31535068
281 + 31534787 = 31535068
311 + 31534757 = 31535068
317 + 31534751 = 31535068
359 + 31534709 = 31535068

Showing the first eight; more decompositions exist.
