Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615242, here are decompositions:

5 + 8615237 = 8615242
11 + 8615231 = 8615242
23 + 8615219 = 8615242
179 + 8615063 = 8615242
191 + 8615051 = 8615242
263 + 8614979 = 8615242
269 + 8614973 = 8615242
353 + 8614889 = 8615242

Showing the first eight; more decompositions exist.
