Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449302, here are decompositions:

13 + 31449289 = 31449302
43 + 31449259 = 31449302
61 + 31449241 = 31449302
139 + 31449163 = 31449302
439 + 31448863 = 31449302
463 + 31448839 = 31449302
499 + 31448803 = 31449302
751 + 31448551 = 31449302

Showing the first eight; more decompositions exist.
