Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662842, here are decompositions:

11 + 8662831 = 8662842
31 + 8662811 = 8662842
43 + 8662799 = 8662842
59 + 8662783 = 8662842
73 + 8662769 = 8662842
113 + 8662729 = 8662842
193 + 8662649 = 8662842
263 + 8662579 = 8662842

Showing the first eight; more decompositions exist.
