Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613842, here are decompositions:

31 + 8613811 = 8613842
103 + 8613739 = 8613842
109 + 8613733 = 8613842
271 + 8613571 = 8613842
283 + 8613559 = 8613842
313 + 8613529 = 8613842
379 + 8613463 = 8613842
421 + 8613421 = 8613842

Showing the first eight; more decompositions exist.
