Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756380, here are decompositions:

23 + 8756357 = 8756380
47 + 8756333 = 8756380
167 + 8756213 = 8756380
179 + 8756201 = 8756380
251 + 8756129 = 8756380
263 + 8756117 = 8756380
317 + 8756063 = 8756380
359 + 8756021 = 8756380

Showing the first eight; more decompositions exist.
