Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504908, here are decompositions:

5 + 31504903 = 31504908
89 + 31504819 = 31504908
107 + 31504801 = 31504908
109 + 31504799 = 31504908
241 + 31504667 = 31504908
257 + 31504651 = 31504908
317 + 31504591 = 31504908
521 + 31504387 = 31504908

Showing the first eight; more decompositions exist.
