Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484834, here are decompositions:

13 + 31484821 = 31484834
37 + 31484797 = 31484834
331 + 31484503 = 31484834
373 + 31484461 = 31484834
421 + 31484413 = 31484834
457 + 31484377 = 31484834
631 + 31484203 = 31484834
673 + 31484161 = 31484834

Showing the first eight; more decompositions exist.
