Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740418, here are decompositions:

7 + 8740411 = 8740418
31 + 8740387 = 8740418
97 + 8740321 = 8740418
199 + 8740219 = 8740418
307 + 8740111 = 8740418
331 + 8740087 = 8740418
457 + 8739961 = 8740418
499 + 8739919 = 8740418

Showing the first eight; more decompositions exist.
