Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454056, here are decompositions:

3 + 31454053 = 31454056
59 + 31453997 = 31454056
113 + 31453943 = 31454056
173 + 31453883 = 31454056
233 + 31453823 = 31454056
479 + 31453577 = 31454056
593 + 31453463 = 31454056
773 + 31453283 = 31454056

Showing the first eight; more decompositions exist.
