Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569422, here are decompositions:

43 + 31569379 = 31569422
103 + 31569319 = 31569422
163 + 31569259 = 31569422
193 + 31569229 = 31569422
229 + 31569193 = 31569422
271 + 31569151 = 31569422
331 + 31569091 = 31569422
349 + 31569073 = 31569422

Showing the first eight; more decompositions exist.
