Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623180, here are decompositions:

107 + 8623073 = 8623180
113 + 8623067 = 8623180
149 + 8623031 = 8623180
197 + 8622983 = 8623180
257 + 8622923 = 8623180
569 + 8622611 = 8623180
617 + 8622563 = 8623180
659 + 8622521 = 8623180

Showing the first eight; more decompositions exist.
