Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534680, here are decompositions:

11 + 31534669 = 31534680
29 + 31534651 = 31534680
43 + 31534637 = 31534680
83 + 31534597 = 31534680
127 + 31534553 = 31534680
137 + 31534543 = 31534680
179 + 31534501 = 31534680
193 + 31534487 = 31534680

Showing the first eight; more decompositions exist.
