Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502924, here are decompositions:

43 + 31502881 = 31502924
67 + 31502857 = 31502924
163 + 31502761 = 31502924
181 + 31502743 = 31502924
223 + 31502701 = 31502924
337 + 31502587 = 31502924
367 + 31502557 = 31502924
571 + 31502353 = 31502924

Showing the first eight; more decompositions exist.
