Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42104, here are decompositions:

3 + 42101 = 42104
31 + 42073 = 42104
43 + 42061 = 42104
61 + 42043 = 42104
151 + 41953 = 42104
157 + 41947 = 42104
163 + 41941 = 42104
193 + 41911 = 42104

Showing the first eight; more decompositions exist.
