Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104228, here are decompositions:

67 + 104161 = 104228
79 + 104149 = 104228
109 + 104119 = 104228
139 + 104089 = 104228
181 + 104047 = 104228
277 + 103951 = 104228
541 + 103687 = 104228
547 + 103681 = 104228

Showing the first eight; more decompositions exist.
