Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665538, here are decompositions:

67 + 8665471 = 8665538
97 + 8665441 = 8665538
109 + 8665429 = 8665538
181 + 8665357 = 8665538
331 + 8665207 = 8665538
337 + 8665201 = 8665538
439 + 8665099 = 8665538
499 + 8665039 = 8665538

Showing the first eight; more decompositions exist.
