Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565654, here are decompositions:

157 + 31565497 = 31565654
163 + 31565491 = 31565654
181 + 31565473 = 31565654
193 + 31565461 = 31565654
223 + 31565431 = 31565654
271 + 31565383 = 31565654
277 + 31565377 = 31565654
331 + 31565323 = 31565654

Showing the first eight; more decompositions exist.
