Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623394, here are decompositions:

37 + 8623357 = 8623394
103 + 8623291 = 8623394
181 + 8623213 = 8623394
271 + 8623123 = 8623394
313 + 8623081 = 8623394
421 + 8622973 = 8623394
523 + 8622871 = 8623394
541 + 8622853 = 8623394

Showing the first eight; more decompositions exist.
