Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636190, here are decompositions:

23 + 8636167 = 8636190
53 + 8636137 = 8636190
61 + 8636129 = 8636190
67 + 8636123 = 8636190
83 + 8636107 = 8636190
97 + 8636093 = 8636190
103 + 8636087 = 8636190
107 + 8636083 = 8636190

Showing the first eight; more decompositions exist.
