Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635990, here are decompositions:

23 + 8635967 = 8635990
71 + 8635919 = 8635990
107 + 8635883 = 8635990
137 + 8635853 = 8635990
173 + 8635817 = 8635990
179 + 8635811 = 8635990
317 + 8635673 = 8635990
353 + 8635637 = 8635990

Showing the first eight; more decompositions exist.
