Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528606, here are decompositions:

47 + 31528559 = 31528606
59 + 31528547 = 31528606
107 + 31528499 = 31528606
173 + 31528433 = 31528606
233 + 31528373 = 31528606
257 + 31528349 = 31528606
269 + 31528337 = 31528606
293 + 31528313 = 31528606

Showing the first eight; more decompositions exist.
