Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528096, here are decompositions:

3 + 31528093 = 31528096
29 + 31528067 = 31528096
59 + 31528037 = 31528096
269 + 31527827 = 31528096
419 + 31527677 = 31528096
563 + 31527533 = 31528096
599 + 31527497 = 31528096
683 + 31527413 = 31528096

Showing the first eight; more decompositions exist.
