Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736972, here are decompositions:

29 + 8736943 = 8736972
53 + 8736919 = 8736972
61 + 8736911 = 8736972
73 + 8736899 = 8736972
89 + 8736883 = 8736972
163 + 8736809 = 8736972
173 + 8736799 = 8736972
191 + 8736781 = 8736972

Showing the first eight; more decompositions exist.
