Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660942, here are decompositions:

13 + 8660929 = 8660942
79 + 8660863 = 8660942
271 + 8660671 = 8660942
331 + 8660611 = 8660942
373 + 8660569 = 8660942
439 + 8660503 = 8660942
523 + 8660419 = 8660942
541 + 8660401 = 8660942

Showing the first eight; more decompositions exist.
