Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528796, here are decompositions:

67 + 31528729 = 31528796
73 + 31528723 = 31528796
127 + 31528669 = 31528796
163 + 31528633 = 31528796
223 + 31528573 = 31528796
337 + 31528459 = 31528796
349 + 31528447 = 31528796
433 + 31528363 = 31528796

Showing the first eight; more decompositions exist.
