Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528496, here are decompositions:

37 + 31528459 = 31528496
229 + 31528267 = 31528496
283 + 31528213 = 31528496
499 + 31527997 = 31528496
709 + 31527787 = 31528496
787 + 31527709 = 31528496
919 + 31527577 = 31528496
997 + 31527499 = 31528496

Showing the first eight; more decompositions exist.
