Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534738, here are decompositions:

29 + 31534709 = 31534738
47 + 31534691 = 31534738
101 + 31534637 = 31534738
107 + 31534631 = 31534738
149 + 31534589 = 31534738
251 + 31534487 = 31534738
281 + 31534457 = 31534738
311 + 31534427 = 31534738

Showing the first eight; more decompositions exist.
