Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623406, here are decompositions:

13 + 8623393 = 8623406
67 + 8623339 = 8623406
157 + 8623249 = 8623406
193 + 8623213 = 8623406
283 + 8623123 = 8623406
367 + 8623039 = 8623406
373 + 8623033 = 8623406
433 + 8622973 = 8623406

Showing the first eight; more decompositions exist.
