Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528732, here are decompositions:

3 + 31528729 = 31528732
173 + 31528559 = 31528732
233 + 31528499 = 31528732
281 + 31528451 = 31528732
359 + 31528373 = 31528732
383 + 31528349 = 31528732
419 + 31528313 = 31528732
449 + 31528283 = 31528732

Showing the first eight; more decompositions exist.
