Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623438, here are decompositions:

29 + 8623409 = 8623438
191 + 8623247 = 8623438
401 + 8623037 = 8623438
419 + 8623019 = 8623438
479 + 8622959 = 8623438
827 + 8622611 = 8623438
947 + 8622491 = 8623438
977 + 8622461 = 8623438

Showing the first eight; more decompositions exist.
