Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743378, here are decompositions:

11 + 8743367 = 8743378
29 + 8743349 = 8743378
47 + 8743331 = 8743378
101 + 8743277 = 8743378
239 + 8743139 = 8743378
257 + 8743121 = 8743378
311 + 8743067 = 8743378
359 + 8743019 = 8743378

Showing the first eight; more decompositions exist.
