Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449606, here are decompositions:

17 + 31449589 = 31449606
29 + 31449577 = 31449606
37 + 31449569 = 31449606
53 + 31449553 = 31449606
79 + 31449527 = 31449606
107 + 31449499 = 31449606
113 + 31449493 = 31449606
127 + 31449479 = 31449606

Showing the first eight; more decompositions exist.
