Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622842, here are decompositions:

31 + 8622811 = 8622842
61 + 8622781 = 8622842
79 + 8622763 = 8622842
313 + 8622529 = 8622842
331 + 8622511 = 8622842
373 + 8622469 = 8622842
379 + 8622463 = 8622842
421 + 8622421 = 8622842

Showing the first eight; more decompositions exist.
