Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449506, here are decompositions:

7 + 31449499 = 31449506
13 + 31449493 = 31449506
43 + 31449463 = 31449506
97 + 31449409 = 31449506
103 + 31449403 = 31449506
379 + 31449127 = 31449506
463 + 31449043 = 31449506
607 + 31448899 = 31449506

Showing the first eight; more decompositions exist.
