Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743228, here are decompositions:

59 + 8743169 = 8743228
89 + 8743139 = 8743228
107 + 8743121 = 8743228
149 + 8743079 = 8743228
191 + 8743037 = 8743228
227 + 8743001 = 8743228
251 + 8742977 = 8743228
311 + 8742917 = 8743228

Showing the first eight; more decompositions exist.
