Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535584, here are decompositions:

167 + 31535417 = 31535584
173 + 31535411 = 31535584
257 + 31535327 = 31535584
263 + 31535321 = 31535584
401 + 31535183 = 31535584
461 + 31535123 = 31535584
503 + 31535081 = 31535584
797 + 31534787 = 31535584

Showing the first eight; more decompositions exist.
