Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615554, here are decompositions:

11 + 8615543 = 8615554
41 + 8615513 = 8615554
47 + 8615507 = 8615554
83 + 8615471 = 8615554
131 + 8615423 = 8615554
281 + 8615273 = 8615554
293 + 8615261 = 8615554
317 + 8615237 = 8615554

Showing the first eight; more decompositions exist.
