Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454866, here are decompositions:

29 + 31454837 = 31454866
83 + 31454783 = 31454866
197 + 31454669 = 31454866
239 + 31454627 = 31454866
353 + 31454513 = 31454866
383 + 31454483 = 31454866
617 + 31454249 = 31454866
647 + 31454219 = 31454866

Showing the first eight; more decompositions exist.
