Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654378, here are decompositions:

79 + 8654299 = 8654378
97 + 8654281 = 8654378
157 + 8654221 = 8654378
331 + 8654047 = 8654378
349 + 8654029 = 8654378
367 + 8654011 = 8654378
487 + 8653891 = 8654378
571 + 8653807 = 8654378

Showing the first eight; more decompositions exist.
