Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637070, here are decompositions:

3 + 8637067 = 8637070
11 + 8637059 = 8637070
17 + 8637053 = 8637070
53 + 8637017 = 8637070
83 + 8636987 = 8637070
149 + 8636921 = 8637070
251 + 8636819 = 8637070
269 + 8636801 = 8637070

Showing the first eight; more decompositions exist.
