Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713440, here are decompositions:

7 + 8713433 = 8713440
11 + 8713429 = 8713440
19 + 8713421 = 8713440
37 + 8713403 = 8713440
41 + 8713399 = 8713440
67 + 8713373 = 8713440
101 + 8713339 = 8713440
137 + 8713303 = 8713440

Showing the first eight; more decompositions exist.
