Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474746, here are decompositions:

13 + 31474733 = 31474746
53 + 31474693 = 31474746
59 + 31474687 = 31474746
73 + 31474673 = 31474746
197 + 31474549 = 31474746
227 + 31474519 = 31474746
257 + 31474489 = 31474746
313 + 31474433 = 31474746

Showing the first eight; more decompositions exist.
