Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756240, here are decompositions:

7 + 8756233 = 8756240
19 + 8756221 = 8756240
37 + 8756203 = 8756240
127 + 8756113 = 8756240
139 + 8756101 = 8756240
151 + 8756089 = 8756240
277 + 8755963 = 8756240
349 + 8755891 = 8756240

Showing the first eight; more decompositions exist.
