Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623340, here are decompositions:

79 + 8623261 = 8623340
127 + 8623213 = 8623340
199 + 8623141 = 8623340
307 + 8623033 = 8623340
337 + 8623003 = 8623340
367 + 8622973 = 8623340
457 + 8622883 = 8623340
463 + 8622877 = 8623340

Showing the first eight; more decompositions exist.
