Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454608, here are decompositions:

167 + 31454441 = 31454608
257 + 31454351 = 31454608
359 + 31454249 = 31454608
389 + 31454219 = 31454608
461 + 31454147 = 31454608
491 + 31454117 = 31454608
617 + 31453991 = 31454608
677 + 31453931 = 31454608

Showing the first eight; more decompositions exist.
