Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535338, here are decompositions:

11 + 31535327 = 31535338
17 + 31535321 = 31535338
167 + 31535171 = 31535338
257 + 31535081 = 31535338
281 + 31535057 = 31535338
467 + 31534871 = 31535338
587 + 31534751 = 31535338
599 + 31534739 = 31535338

Showing the first eight; more decompositions exist.
