Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454946, here are decompositions:

23 + 31454923 = 31454946
37 + 31454909 = 31454946
43 + 31454903 = 31454946
73 + 31454873 = 31454946
79 + 31454867 = 31454946
109 + 31454837 = 31454946
137 + 31454809 = 31454946
163 + 31454783 = 31454946

Showing the first eight; more decompositions exist.
