Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529978, here are decompositions:

79 + 31529899 = 31529978
97 + 31529881 = 31529978
229 + 31529749 = 31529978
307 + 31529671 = 31529978
349 + 31529629 = 31529978
421 + 31529557 = 31529978
439 + 31529539 = 31529978
457 + 31529521 = 31529978

Showing the first eight; more decompositions exist.
