Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454974, here are decompositions:

3 + 31454971 = 31454974
17 + 31454957 = 31454974
71 + 31454903 = 31454974
101 + 31454873 = 31454974
107 + 31454867 = 31454974
137 + 31454837 = 31454974
191 + 31454783 = 31454974
233 + 31454741 = 31454974

Showing the first eight; more decompositions exist.
