Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534974, here are decompositions:

13 + 31534961 = 31534974
61 + 31534913 = 31534974
101 + 31534873 = 31534974
103 + 31534871 = 31534974
173 + 31534801 = 31534974
223 + 31534751 = 31534974
283 + 31534691 = 31534974
337 + 31534637 = 31534974

Showing the first eight; more decompositions exist.
