Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611942, here are decompositions:

83 + 8611859 = 8611942
113 + 8611829 = 8611942
149 + 8611793 = 8611942
233 + 8611709 = 8611942
239 + 8611703 = 8611942
263 + 8611679 = 8611942
419 + 8611523 = 8611942
503 + 8611439 = 8611942

Showing the first eight; more decompositions exist.
