Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741478, here are decompositions:

7 + 8741471 = 8741478
19 + 8741459 = 8741478
41 + 8741437 = 8741478
47 + 8741431 = 8741478
107 + 8741371 = 8741478
131 + 8741347 = 8741478
149 + 8741329 = 8741478
157 + 8741321 = 8741478

Showing the first eight; more decompositions exist.
