Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734140, here are decompositions:

47 + 8734093 = 8734140
61 + 8734079 = 8734140
71 + 8734069 = 8734140
89 + 8734051 = 8734140
113 + 8734027 = 8734140
127 + 8734013 = 8734140
139 + 8734001 = 8734140
199 + 8733941 = 8734140

Showing the first eight; more decompositions exist.
