Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740648, here are decompositions:

5 + 8740643 = 8740648
41 + 8740607 = 8740648
71 + 8740577 = 8740648
89 + 8740559 = 8740648
107 + 8740541 = 8740648
131 + 8740517 = 8740648
281 + 8740367 = 8740648
311 + 8740337 = 8740648

Showing the first eight; more decompositions exist.
