Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615232, here are decompositions:

13 + 8615219 = 8615232
71 + 8615161 = 8615232
83 + 8615149 = 8615232
149 + 8615083 = 8615232
181 + 8615051 = 8615232
281 + 8614951 = 8615232
293 + 8614939 = 8615232
331 + 8614901 = 8615232

Showing the first eight; more decompositions exist.
