Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449608, here are decompositions:

19 + 31449589 = 31449608
31 + 31449577 = 31449608
37 + 31449571 = 31449608
109 + 31449499 = 31449608
199 + 31449409 = 31449608
349 + 31449259 = 31449608
367 + 31449241 = 31449608
571 + 31449037 = 31449608

Showing the first eight; more decompositions exist.
