Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741438, here are decompositions:

7 + 8741431 = 8741438
37 + 8741401 = 8741438
67 + 8741371 = 8741438
109 + 8741329 = 8741438
367 + 8741071 = 8741438
397 + 8741041 = 8741438
439 + 8740999 = 8741438
487 + 8740951 = 8741438

Showing the first eight; more decompositions exist.
