Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740138, here are decompositions:

41 + 8740097 = 8740138
101 + 8740037 = 8740138
227 + 8739911 = 8740138
269 + 8739869 = 8740138
311 + 8739827 = 8740138
317 + 8739821 = 8740138
389 + 8739749 = 8740138
467 + 8739671 = 8740138

Showing the first eight; more decompositions exist.
