Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529728, here are decompositions:

11 + 31529717 = 31529728
47 + 31529681 = 31529728
59 + 31529669 = 31529728
257 + 31529471 = 31529728
281 + 31529447 = 31529728
449 + 31529279 = 31529728
479 + 31529249 = 31529728
509 + 31529219 = 31529728

Showing the first eight; more decompositions exist.
