Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623442, here are decompositions:

13 + 8623429 = 8623442
19 + 8623423 = 8623442
103 + 8623339 = 8623442
151 + 8623291 = 8623442
181 + 8623261 = 8623442
193 + 8623249 = 8623442
229 + 8623213 = 8623442
409 + 8623033 = 8623442

Showing the first eight; more decompositions exist.
