Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535034, here are decompositions:

23 + 31535011 = 31535034
53 + 31534981 = 31535034
73 + 31534961 = 31535034
163 + 31534871 = 31535034
233 + 31534801 = 31535034
277 + 31534757 = 31535034
281 + 31534753 = 31535034
283 + 31534751 = 31535034

Showing the first eight; more decompositions exist.
