Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623988, here are decompositions:

19 + 8623969 = 8623988
157 + 8623831 = 8623988
181 + 8623807 = 8623988
271 + 8623717 = 8623988
337 + 8623651 = 8623988
349 + 8623639 = 8623988
367 + 8623621 = 8623988
409 + 8623579 = 8623988

Showing the first eight; more decompositions exist.
