Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527794, here are decompositions:

7 + 31527787 = 31527794
13 + 31527781 = 31527794
97 + 31527697 = 31527794
211 + 31527583 = 31527794
271 + 31527523 = 31527794
313 + 31527481 = 31527794
541 + 31527253 = 31527794
547 + 31527247 = 31527794

Showing the first eight; more decompositions exist.
