Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474466, here are decompositions:

43 + 31474423 = 31474466
103 + 31474363 = 31474466
109 + 31474357 = 31474466
337 + 31474129 = 31474466
409 + 31474057 = 31474466
433 + 31474033 = 31474466
619 + 31473847 = 31474466
733 + 31473733 = 31474466

Showing the first eight; more decompositions exist.
