Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623178, here are decompositions:

37 + 8623141 = 8623178
97 + 8623081 = 8623178
127 + 8623051 = 8623178
139 + 8623039 = 8623178
307 + 8622871 = 8623178
331 + 8622847 = 8623178
337 + 8622841 = 8623178
367 + 8622811 = 8623178

Showing the first eight; more decompositions exist.
