Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530026, here are decompositions:

103 + 31529923 = 31530026
127 + 31529899 = 31530026
277 + 31529749 = 31530026
349 + 31529677 = 31530026
397 + 31529629 = 31530026
433 + 31529593 = 31530026
487 + 31529539 = 31530026
547 + 31529479 = 31530026

Showing the first eight; more decompositions exist.
