Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741858, here are decompositions:

19 + 8741839 = 8741858
61 + 8741797 = 8741858
79 + 8741779 = 8741858
109 + 8741749 = 8741858
337 + 8741521 = 8741858
379 + 8741479 = 8741858
421 + 8741437 = 8741858
457 + 8741401 = 8741858

Showing the first eight; more decompositions exist.
