Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504814, here are decompositions:

13 + 31504801 = 31504814
31 + 31504783 = 31504814
67 + 31504747 = 31504814
163 + 31504651 = 31504814
223 + 31504591 = 31504814
241 + 31504573 = 31504814
457 + 31504357 = 31504814
463 + 31504351 = 31504814

Showing the first eight; more decompositions exist.
