Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671236, here are decompositions:

5 + 8671231 = 8671236
17 + 8671219 = 8671236
43 + 8671193 = 8671236
59 + 8671177 = 8671236
89 + 8671147 = 8671236
103 + 8671133 = 8671236
109 + 8671127 = 8671236
137 + 8671099 = 8671236

Showing the first eight; more decompositions exist.
