Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485674, here are decompositions:

13 + 31485661 = 31485674
277 + 31485397 = 31485674
373 + 31485301 = 31485674
397 + 31485277 = 31485674
607 + 31485067 = 31485674
643 + 31485031 = 31485674
673 + 31485001 = 31485674
733 + 31484941 = 31485674

Showing the first eight; more decompositions exist.
