Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740144, here are decompositions:

5 + 8740139 = 8740144
47 + 8740097 = 8740144
107 + 8740037 = 8740144
191 + 8739953 = 8740144
227 + 8739917 = 8740144
233 + 8739911 = 8740144
293 + 8739851 = 8740144
317 + 8739827 = 8740144

Showing the first eight; more decompositions exist.
