Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734378, here are decompositions:

5 + 8734373 = 8734378
11 + 8734367 = 8734378
17 + 8734361 = 8734378
131 + 8734247 = 8734378
167 + 8734211 = 8734378
179 + 8734199 = 8734378
449 + 8733929 = 8734378
479 + 8733899 = 8734378

Showing the first eight; more decompositions exist.
