Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741390, here are decompositions:

19 + 8741371 = 8741390
37 + 8741353 = 8741390
43 + 8741347 = 8741390
61 + 8741329 = 8741390
139 + 8741251 = 8741390
157 + 8741233 = 8741390
199 + 8741191 = 8741390
241 + 8741149 = 8741390

Showing the first eight; more decompositions exist.
