Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538024, here are decompositions:

43 + 31537981 = 31538024
103 + 31537921 = 31538024
163 + 31537861 = 31538024
181 + 31537843 = 31538024
277 + 31537747 = 31538024
283 + 31537741 = 31538024
307 + 31537717 = 31538024
337 + 31537687 = 31538024

Showing the first eight; more decompositions exist.
