Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474946, here are decompositions:

73 + 31474873 = 31474946
79 + 31474867 = 31474946
163 + 31474783 = 31474946
199 + 31474747 = 31474946
277 + 31474669 = 31474946
397 + 31474549 = 31474946
457 + 31474489 = 31474946
523 + 31474423 = 31474946

Showing the first eight; more decompositions exist.
