Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705242, here are decompositions:

5 + 8705237 = 8705242
23 + 8705219 = 8705242
59 + 8705183 = 8705242
71 + 8705171 = 8705242
83 + 8705159 = 8705242
131 + 8705111 = 8705242
149 + 8705093 = 8705242
173 + 8705069 = 8705242

Showing the first eight; more decompositions exist.
