Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641942, here are decompositions:

59 + 8641883 = 8641942
233 + 8641709 = 8641942
269 + 8641673 = 8641942
311 + 8641631 = 8641942
401 + 8641541 = 8641942
509 + 8641433 = 8641942
521 + 8641421 = 8641942
593 + 8641349 = 8641942

Showing the first eight; more decompositions exist.
