Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746240, here are decompositions:

3 + 8746237 = 8746240
11 + 8746229 = 8746240
17 + 8746223 = 8746240
47 + 8746193 = 8746240
311 + 8745929 = 8746240
317 + 8745923 = 8746240
359 + 8745881 = 8746240
383 + 8745857 = 8746240

Showing the first eight; more decompositions exist.
