Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534910, here are decompositions:

31 + 31534879 = 31534910
37 + 31534873 = 31534910
79 + 31534831 = 31534910
109 + 31534801 = 31534910
157 + 31534753 = 31534910
181 + 31534729 = 31534910
241 + 31534669 = 31534910
313 + 31534597 = 31534910

Showing the first eight; more decompositions exist.
