Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726380, here are decompositions:

17 + 8726363 = 8726380
23 + 8726357 = 8726380
29 + 8726351 = 8726380
107 + 8726273 = 8726380
137 + 8726243 = 8726380
239 + 8726141 = 8726380
293 + 8726087 = 8726380
317 + 8726063 = 8726380

Showing the first eight; more decompositions exist.
