Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736378, here are decompositions:

11 + 8736367 = 8736378
37 + 8736341 = 8736378
179 + 8736199 = 8736378
191 + 8736187 = 8736378
199 + 8736179 = 8736378
239 + 8736139 = 8736378
251 + 8736127 = 8736378
269 + 8736109 = 8736378

Showing the first eight; more decompositions exist.
