Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499474, here are decompositions:

7 + 31499467 = 31499474
43 + 31499431 = 31499474
67 + 31499407 = 31499474
73 + 31499401 = 31499474
103 + 31499371 = 31499474
151 + 31499323 = 31499474
163 + 31499311 = 31499474
313 + 31499161 = 31499474

Showing the first eight; more decompositions exist.
