Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684242, here are decompositions:

11 + 8684231 = 8684242
29 + 8684213 = 8684242
41 + 8684201 = 8684242
53 + 8684189 = 8684242
71 + 8684171 = 8684242
131 + 8684111 = 8684242
173 + 8684069 = 8684242
191 + 8684051 = 8684242

Showing the first eight; more decompositions exist.
