Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477024, here are decompositions:

3 + 31477021 = 31477024
107 + 31476917 = 31477024
281 + 31476743 = 31477024
401 + 31476623 = 31477024
431 + 31476593 = 31477024
563 + 31476461 = 31477024
587 + 31476437 = 31477024
641 + 31476383 = 31477024

Showing the first eight; more decompositions exist.
