Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619042, here are decompositions:

11 + 8619031 = 8619042
43 + 8618999 = 8619042
83 + 8618959 = 8619042
109 + 8618933 = 8619042
149 + 8618893 = 8619042
163 + 8618879 = 8619042
181 + 8618861 = 8619042
191 + 8618851 = 8619042

Showing the first eight; more decompositions exist.
