Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741228, here are decompositions:

37 + 8741191 = 8741228
79 + 8741149 = 8741228
109 + 8741119 = 8741228
157 + 8741071 = 8741228
229 + 8740999 = 8741228
277 + 8740951 = 8741228
337 + 8740891 = 8741228
421 + 8740807 = 8741228

Showing the first eight; more decompositions exist.
