Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528552, here are decompositions:

5 + 31528547 = 31528552
53 + 31528499 = 31528552
101 + 31528451 = 31528552
179 + 31528373 = 31528552
239 + 31528313 = 31528552
269 + 31528283 = 31528552
311 + 31528241 = 31528552
383 + 31528169 = 31528552

Showing the first eight; more decompositions exist.
