Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504874, here are decompositions:

73 + 31504801 = 31504874
127 + 31504747 = 31504874
223 + 31504651 = 31504874
283 + 31504591 = 31504874
307 + 31504567 = 31504874
421 + 31504453 = 31504874
487 + 31504387 = 31504874
523 + 31504351 = 31504874

Showing the first eight; more decompositions exist.
