Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661348, here are decompositions:

37 + 8661311 = 8661348
67 + 8661281 = 8661348
97 + 8661251 = 8661348
107 + 8661241 = 8661348
109 + 8661239 = 8661348
131 + 8661217 = 8661348
151 + 8661197 = 8661348
167 + 8661181 = 8661348

Showing the first eight; more decompositions exist.
