Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542474, here are decompositions:

17 + 31542457 = 31542474
37 + 31542437 = 31542474
83 + 31542391 = 31542474
97 + 31542377 = 31542474
101 + 31542373 = 31542474
151 + 31542323 = 31542474
193 + 31542281 = 31542474
241 + 31542233 = 31542474

Showing the first eight; more decompositions exist.
