Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529108, here are decompositions:

19 + 31529089 = 31529108
139 + 31528969 = 31529108
199 + 31528909 = 31529108
277 + 31528831 = 31529108
307 + 31528801 = 31529108
367 + 31528741 = 31529108
379 + 31528729 = 31529108
439 + 31528669 = 31529108

Showing the first eight; more decompositions exist.
