Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533076, here are decompositions:

137 + 31532939 = 31533076
383 + 31532693 = 31533076
389 + 31532687 = 31533076
479 + 31532597 = 31533076
503 + 31532573 = 31533076
569 + 31532507 = 31533076
587 + 31532489 = 31533076
599 + 31532477 = 31533076

Showing the first eight; more decompositions exist.
