Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740378, here are decompositions:

5 + 8740373 = 8740378
11 + 8740367 = 8740378
41 + 8740337 = 8740378
47 + 8740331 = 8740378
89 + 8740289 = 8740378
191 + 8740187 = 8740378
239 + 8740139 = 8740378
281 + 8740097 = 8740378

Showing the first eight; more decompositions exist.
