Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615398, here are decompositions:

131 + 8615267 = 8615398
137 + 8615261 = 8615398
167 + 8615231 = 8615398
179 + 8615219 = 8615398
347 + 8615051 = 8615398
419 + 8614979 = 8615398
431 + 8614967 = 8615398
509 + 8614889 = 8615398

Showing the first eight; more decompositions exist.
