Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605120, here are decompositions:

59 + 8605061 = 8605120
101 + 8605019 = 8605120
137 + 8604983 = 8605120
257 + 8604863 = 8605120
311 + 8604809 = 8605120
353 + 8604767 = 8605120
431 + 8604689 = 8605120
479 + 8604641 = 8605120

Showing the first eight; more decompositions exist.
