Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756390, here are decompositions:

67 + 8756323 = 8756390
73 + 8756317 = 8756390
127 + 8756263 = 8756390
151 + 8756239 = 8756390
157 + 8756233 = 8756390
241 + 8756149 = 8756390
271 + 8756119 = 8756390
277 + 8756113 = 8756390

Showing the first eight; more decompositions exist.
