Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615542, here are decompositions:

3 + 8615539 = 8615542
29 + 8615513 = 8615542
71 + 8615471 = 8615542
263 + 8615279 = 8615542
269 + 8615273 = 8615542
281 + 8615261 = 8615542
311 + 8615231 = 8615542
443 + 8615099 = 8615542

Showing the first eight; more decompositions exist.
