Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528762, here are decompositions:

11 + 31528751 = 31528762
149 + 31528613 = 31528762
263 + 31528499 = 31528762
311 + 31528451 = 31528762
389 + 31528373 = 31528762
449 + 31528313 = 31528762
479 + 31528283 = 31528762
521 + 31528241 = 31528762

Showing the first eight; more decompositions exist.
