Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623142, here are decompositions:

19 + 8623123 = 8623142
61 + 8623081 = 8623142
103 + 8623039 = 8623142
109 + 8623033 = 8623142
139 + 8623003 = 8623142
271 + 8622871 = 8623142
331 + 8622811 = 8623142
349 + 8622793 = 8623142

Showing the first eight; more decompositions exist.
