Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454422, here are decompositions:

71 + 31454351 = 31454422
101 + 31454321 = 31454422
173 + 31454249 = 31454422
431 + 31453991 = 31454422
479 + 31453943 = 31454422
491 + 31453931 = 31454422
599 + 31453823 = 31454422
743 + 31453679 = 31454422

Showing the first eight; more decompositions exist.
