Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533082, here are decompositions:

83 + 31532999 = 31533082
101 + 31532981 = 31533082
389 + 31532693 = 31533082
443 + 31532639 = 31533082
509 + 31532573 = 31533082
593 + 31532489 = 31533082
653 + 31532429 = 31533082
743 + 31532339 = 31533082

Showing the first eight; more decompositions exist.
