Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504926, here are decompositions:

17 + 31504909 = 31504926
23 + 31504903 = 31504926
43 + 31504883 = 31504926
53 + 31504873 = 31504926
107 + 31504819 = 31504926
127 + 31504799 = 31504926
179 + 31504747 = 31504926
223 + 31504703 = 31504926

Showing the first eight; more decompositions exist.
