Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623478, here are decompositions:

139 + 8623339 = 8623478
229 + 8623249 = 8623478
337 + 8623141 = 8623478
397 + 8623081 = 8623478
439 + 8623039 = 8623478
601 + 8622877 = 8623478
607 + 8622871 = 8623478
631 + 8622847 = 8623478

Showing the first eight; more decompositions exist.
