Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615842, here are decompositions:

71 + 8615771 = 8615842
149 + 8615693 = 8615842
251 + 8615591 = 8615842
419 + 8615423 = 8615842
509 + 8615333 = 8615842
563 + 8615279 = 8615842
569 + 8615273 = 8615842
743 + 8615099 = 8615842

Showing the first eight; more decompositions exist.
