Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708380, here are decompositions:

41 + 8708339 = 8708380
89 + 8708291 = 8708380
179 + 8708201 = 8708380
227 + 8708153 = 8708380
251 + 8708129 = 8708380
293 + 8708087 = 8708380
311 + 8708069 = 8708380
383 + 8707997 = 8708380

Showing the first eight; more decompositions exist.
