Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529996, here are decompositions:

19 + 31529977 = 31529996
73 + 31529923 = 31529996
97 + 31529899 = 31529996
367 + 31529629 = 31529996
373 + 31529623 = 31529996
439 + 31529557 = 31529996
457 + 31529539 = 31529996
643 + 31529353 = 31529996

Showing the first eight; more decompositions exist.
