Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534494, here are decompositions:

7 + 31534487 = 31534494
11 + 31534483 = 31534494
37 + 31534457 = 31534494
53 + 31534441 = 31534494
67 + 31534427 = 31534494
71 + 31534423 = 31534494
83 + 31534411 = 31534494
151 + 31534343 = 31534494

Showing the first eight; more decompositions exist.
