Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740228, here are decompositions:

41 + 8740187 = 8740228
59 + 8740169 = 8740228
71 + 8740157 = 8740228
89 + 8740139 = 8740228
131 + 8740097 = 8740228
191 + 8740037 = 8740228
311 + 8739917 = 8740228
317 + 8739911 = 8740228

Showing the first eight; more decompositions exist.
