Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662138, here are decompositions:

5 + 8662133 = 8662138
11 + 8662127 = 8662138
29 + 8662109 = 8662138
47 + 8662091 = 8662138
59 + 8662079 = 8662138
101 + 8662037 = 8662138
197 + 8661941 = 8662138
239 + 8661899 = 8662138

Showing the first eight; more decompositions exist.
