Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623078, here are decompositions:

5 + 8623073 = 8623078
11 + 8623067 = 8623078
17 + 8623061 = 8623078
41 + 8623037 = 8623078
47 + 8623031 = 8623078
59 + 8623019 = 8623078
311 + 8622767 = 8623078
467 + 8622611 = 8623078

Showing the first eight; more decompositions exist.
