Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741786, here are decompositions:

7 + 8741779 = 8741786
37 + 8741749 = 8741786
43 + 8741743 = 8741786
103 + 8741683 = 8741786
223 + 8741563 = 8741786
283 + 8741503 = 8741786
307 + 8741479 = 8741786
349 + 8741437 = 8741786

Showing the first eight; more decompositions exist.
