Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741820, here are decompositions:

7 + 8741813 = 8741820
19 + 8741801 = 8741820
23 + 8741797 = 8741820
41 + 8741779 = 8741820
67 + 8741753 = 8741820
71 + 8741749 = 8741820
79 + 8741741 = 8741820
137 + 8741683 = 8741820

Showing the first eight; more decompositions exist.
