Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653842, here are decompositions:

31 + 8653811 = 8653842
53 + 8653789 = 8653842
73 + 8653769 = 8653842
79 + 8653763 = 8653842
101 + 8653741 = 8653842
139 + 8653703 = 8653842
151 + 8653691 = 8653842
163 + 8653679 = 8653842

Showing the first eight; more decompositions exist.
