Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527926, here are decompositions:

13 + 31527913 = 31527926
97 + 31527829 = 31527926
109 + 31527817 = 31527926
139 + 31527787 = 31527926
223 + 31527703 = 31527926
229 + 31527697 = 31527926
349 + 31527577 = 31527926
673 + 31527253 = 31527926

Showing the first eight; more decompositions exist.
