Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740072, here are decompositions:

251 + 8739821 = 8740072
269 + 8739803 = 8740072
359 + 8739713 = 8740072
401 + 8739671 = 8740072
449 + 8739623 = 8740072
569 + 8739503 = 8740072
641 + 8739431 = 8740072
683 + 8739389 = 8740072

Showing the first eight; more decompositions exist.
