Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741186, here are decompositions:

37 + 8741149 = 8741186
43 + 8741143 = 8741186
67 + 8741119 = 8741186
193 + 8740993 = 8741186
379 + 8740807 = 8741186
397 + 8740789 = 8741186
607 + 8740579 = 8741186
733 + 8740453 = 8741186

Showing the first eight; more decompositions exist.
