Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504914, here are decompositions:

5 + 31504909 = 31504914
11 + 31504903 = 31504914
31 + 31504883 = 31504914
41 + 31504873 = 31504914
113 + 31504801 = 31504914
131 + 31504783 = 31504914
167 + 31504747 = 31504914
211 + 31504703 = 31504914

Showing the first eight; more decompositions exist.
