Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752378, here are decompositions:

17 + 8752361 = 8752378
191 + 8752187 = 8752378
197 + 8752181 = 8752378
311 + 8752067 = 8752378
347 + 8752031 = 8752378
491 + 8751887 = 8752378
821 + 8751557 = 8752378
911 + 8751467 = 8752378

Showing the first eight; more decompositions exist.
