Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504674, here are decompositions:

7 + 31504667 = 31504674
13 + 31504661 = 31504674
23 + 31504651 = 31504674
67 + 31504607 = 31504674
83 + 31504591 = 31504674
101 + 31504573 = 31504674
107 + 31504567 = 31504674
127 + 31504547 = 31504674

Showing the first eight; more decompositions exist.
