Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528024, here are decompositions:

5 + 31528019 = 31528024
23 + 31528001 = 31528024
83 + 31527941 = 31528024
137 + 31527887 = 31528024
197 + 31527827 = 31528024
347 + 31527677 = 31528024
491 + 31527533 = 31528024
503 + 31527521 = 31528024

Showing the first eight; more decompositions exist.
