Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615412, here are decompositions:

23 + 8615389 = 8615412
79 + 8615333 = 8615412
89 + 8615323 = 8615412
139 + 8615273 = 8615412
151 + 8615261 = 8615412
181 + 8615231 = 8615412
193 + 8615219 = 8615412
251 + 8615161 = 8615412

Showing the first eight; more decompositions exist.
