Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623580, here are decompositions:

61 + 8623519 = 8623580
151 + 8623429 = 8623580
157 + 8623423 = 8623580
223 + 8623357 = 8623580
241 + 8623339 = 8623580
331 + 8623249 = 8623580
367 + 8623213 = 8623580
439 + 8623141 = 8623580

Showing the first eight; more decompositions exist.
