Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623480, here are decompositions:

71 + 8623409 = 8623480
227 + 8623253 = 8623480
233 + 8623247 = 8623480
419 + 8623061 = 8623480
443 + 8623037 = 8623480
449 + 8623031 = 8623480
461 + 8623019 = 8623480
521 + 8622959 = 8623480

Showing the first eight; more decompositions exist.
