Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741838, here are decompositions:

37 + 8741801 = 8741838
41 + 8741797 = 8741838
59 + 8741779 = 8741838
89 + 8741749 = 8741838
97 + 8741741 = 8741838
139 + 8741699 = 8741838
151 + 8741687 = 8741838
197 + 8741641 = 8741838

Showing the first eight; more decompositions exist.
