Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529318, here are decompositions:

61 + 31529257 = 31529318
151 + 31529167 = 31529318
211 + 31529107 = 31529318
229 + 31529089 = 31529318
349 + 31528969 = 31529318
409 + 31528909 = 31529318
487 + 31528831 = 31529318
577 + 31528741 = 31529318

Showing the first eight; more decompositions exist.
