Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454950, here are decompositions:

41 + 31454909 = 31454950
47 + 31454903 = 31454950
83 + 31454867 = 31454950
113 + 31454837 = 31454950
167 + 31454783 = 31454950
269 + 31454681 = 31454950
281 + 31454669 = 31454950
467 + 31454483 = 31454950

Showing the first eight; more decompositions exist.
