Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733978, here are decompositions:

37 + 8733941 = 8733978
79 + 8733899 = 8733978
89 + 8733889 = 8733978
107 + 8733871 = 8733978
139 + 8733839 = 8733978
151 + 8733827 = 8733978
157 + 8733821 = 8733978
167 + 8733811 = 8733978

Showing the first eight; more decompositions exist.
