Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42054, here are decompositions:

11 + 42043 = 42054
31 + 42023 = 42054
37 + 42017 = 42054
41 + 42013 = 42054
71 + 41983 = 42054
73 + 41981 = 42054
97 + 41957 = 42054
101 + 41953 = 42054

Showing the first eight; more decompositions exist.
