Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449332, here are decompositions:

43 + 31449289 = 31449332
73 + 31449259 = 31449332
433 + 31448899 = 31449332
613 + 31448719 = 31449332
619 + 31448713 = 31449332
751 + 31448581 = 31449332
853 + 31448479 = 31449332
883 + 31448449 = 31449332

Showing the first eight; more decompositions exist.
