Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736042, here are decompositions:

5 + 8736037 = 8736042
41 + 8736001 = 8736042
71 + 8735971 = 8736042
101 + 8735941 = 8736042
109 + 8735933 = 8736042
151 + 8735891 = 8736042
163 + 8735879 = 8736042
181 + 8735861 = 8736042

Showing the first eight; more decompositions exist.
