Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42904, here are decompositions:

3 + 42901 = 42904
5 + 42899 = 42904
41 + 42863 = 42904
83 + 42821 = 42904
107 + 42797 = 42904
131 + 42773 = 42904
137 + 42767 = 42904
167 + 42737 = 42904

Showing the first eight; more decompositions exist.
