Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610242, here are decompositions:

13 + 8610229 = 8610242
73 + 8610169 = 8610242
103 + 8610139 = 8610242
181 + 8610061 = 8610242
241 + 8610001 = 8610242
331 + 8609911 = 8610242
409 + 8609833 = 8610242
523 + 8609719 = 8610242

Showing the first eight; more decompositions exist.
