Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454836, here are decompositions:

53 + 31454783 = 31454836
167 + 31454669 = 31454836
353 + 31454483 = 31454836
587 + 31454249 = 31454836
617 + 31454219 = 31454836
719 + 31454117 = 31454836
839 + 31453997 = 31454836
953 + 31453883 = 31454836

Showing the first eight; more decompositions exist.
