Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627842, here are decompositions:

29 + 8627813 = 8627842
101 + 8627741 = 8627842
149 + 8627693 = 8627842
233 + 8627609 = 8627842
239 + 8627603 = 8627842
269 + 8627573 = 8627842
281 + 8627561 = 8627842
401 + 8627441 = 8627842

Showing the first eight; more decompositions exist.
