Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741540, here are decompositions:

7 + 8741533 = 8741540
19 + 8741521 = 8741540
37 + 8741503 = 8741540
61 + 8741479 = 8741540
103 + 8741437 = 8741540
109 + 8741431 = 8741540
139 + 8741401 = 8741540
193 + 8741347 = 8741540

Showing the first eight; more decompositions exist.
