Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449664, here are decompositions:

17 + 31449647 = 31449664
53 + 31449611 = 31449664
83 + 31449581 = 31449664
107 + 31449557 = 31449664
137 + 31449527 = 31449664
263 + 31449401 = 31449664
401 + 31449263 = 31449664
431 + 31449233 = 31449664

Showing the first eight; more decompositions exist.
