Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623226, here are decompositions:

13 + 8623213 = 8623226
103 + 8623123 = 8623226
193 + 8623033 = 8623226
223 + 8623003 = 8623226
349 + 8622877 = 8623226
373 + 8622853 = 8623226
379 + 8622847 = 8623226
433 + 8622793 = 8623226

Showing the first eight; more decompositions exist.
