Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623450, here are decompositions:

41 + 8623409 = 8623450
131 + 8623319 = 8623450
197 + 8623253 = 8623450
257 + 8623193 = 8623450
347 + 8623103 = 8623450
383 + 8623067 = 8623450
389 + 8623061 = 8623450
419 + 8623031 = 8623450

Showing the first eight; more decompositions exist.
