Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637190, here are decompositions:

11 + 8637179 = 8637190
59 + 8637131 = 8637190
71 + 8637119 = 8637190
83 + 8637107 = 8637190
131 + 8637059 = 8637190
137 + 8637053 = 8637190
173 + 8637017 = 8637190
269 + 8636921 = 8637190

Showing the first eight; more decompositions exist.
