Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623190, here are decompositions:

67 + 8623123 = 8623190
109 + 8623081 = 8623190
139 + 8623051 = 8623190
151 + 8623039 = 8623190
157 + 8623033 = 8623190
307 + 8622883 = 8623190
313 + 8622877 = 8623190
337 + 8622853 = 8623190

Showing the first eight; more decompositions exist.
