Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588924, here are decompositions:

251 + 31588673 = 31588924
281 + 31588643 = 31588924
293 + 31588631 = 31588924
317 + 31588607 = 31588924
401 + 31588523 = 31588924
431 + 31588493 = 31588924
461 + 31588463 = 31588924
557 + 31588367 = 31588924

Showing the first eight; more decompositions exist.
