Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623946, here are decompositions:

7 + 8623939 = 8623946
43 + 8623903 = 8623946
103 + 8623843 = 8623946
139 + 8623807 = 8623946
229 + 8623717 = 8623946
307 + 8623639 = 8623946
367 + 8623579 = 8623946
523 + 8623423 = 8623946

Showing the first eight; more decompositions exist.
