Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528594, here are decompositions:

47 + 31528547 = 31528594
257 + 31528337 = 31528594
281 + 31528313 = 31528594
311 + 31528283 = 31528594
353 + 31528241 = 31528594
443 + 31528151 = 31528594
467 + 31528127 = 31528594
491 + 31528103 = 31528594

Showing the first eight; more decompositions exist.
