Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665544, here are decompositions:

3 + 8665541 = 8665544
73 + 8665471 = 8665544
103 + 8665441 = 8665544
211 + 8665333 = 8665544
241 + 8665303 = 8665544
337 + 8665207 = 8665544
397 + 8665147 = 8665544
421 + 8665123 = 8665544

Showing the first eight; more decompositions exist.
