Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736990, here are decompositions:

47 + 8736943 = 8736990
71 + 8736919 = 8736990
79 + 8736911 = 8736990
83 + 8736907 = 8736990
107 + 8736883 = 8736990
109 + 8736881 = 8736990
137 + 8736853 = 8736990
173 + 8736817 = 8736990

Showing the first eight; more decompositions exist.
