Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8714440, here are decompositions:

3 + 8714437 = 8714440
11 + 8714429 = 8714440
23 + 8714417 = 8714440
47 + 8714393 = 8714440
83 + 8714357 = 8714440
101 + 8714339 = 8714440
107 + 8714333 = 8714440
149 + 8714291 = 8714440

Showing the first eight; more decompositions exist.
