Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617842, here are decompositions:

5 + 8617837 = 8617842
19 + 8617823 = 8617842
43 + 8617799 = 8617842
73 + 8617769 = 8617842
89 + 8617753 = 8617842
139 + 8617703 = 8617842
281 + 8617561 = 8617842
293 + 8617549 = 8617842

Showing the first eight; more decompositions exist.
