Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741388, here are decompositions:

17 + 8741371 = 8741388
41 + 8741347 = 8741388
59 + 8741329 = 8741388
67 + 8741321 = 8741388
79 + 8741309 = 8741388
109 + 8741279 = 8741388
137 + 8741251 = 8741388
157 + 8741231 = 8741388

Showing the first eight; more decompositions exist.
