Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623166, here are decompositions:

43 + 8623123 = 8623166
127 + 8623039 = 8623166
163 + 8623003 = 8623166
193 + 8622973 = 8623166
283 + 8622883 = 8623166
313 + 8622853 = 8623166
373 + 8622793 = 8623166
787 + 8622379 = 8623166

Showing the first eight; more decompositions exist.
