Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623072, here are decompositions:

5 + 8623067 = 8623072
11 + 8623061 = 8623072
41 + 8623031 = 8623072
53 + 8623019 = 8623072
89 + 8622983 = 8623072
113 + 8622959 = 8623072
149 + 8622923 = 8623072
389 + 8622683 = 8623072

Showing the first eight; more decompositions exist.
