Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734128, here are decompositions:

59 + 8734069 = 8734128
101 + 8734027 = 8734128
107 + 8734021 = 8734128
127 + 8734001 = 8734128
149 + 8733979 = 8734128
199 + 8733929 = 8734128
229 + 8733899 = 8734128
239 + 8733889 = 8734128

Showing the first eight; more decompositions exist.
