Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615452, here are decompositions:

29 + 8615423 = 8615452
173 + 8615279 = 8615452
179 + 8615273 = 8615452
191 + 8615261 = 8615452
233 + 8615219 = 8615452
353 + 8615099 = 8615452
389 + 8615063 = 8615452
401 + 8615051 = 8615452

Showing the first eight; more decompositions exist.
