Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722378, here are decompositions:

11 + 8722367 = 8722378
17 + 8722361 = 8722378
47 + 8722331 = 8722378
167 + 8722211 = 8722378
191 + 8722187 = 8722378
281 + 8722097 = 8722378
359 + 8722019 = 8722378
389 + 8721989 = 8722378

Showing the first eight; more decompositions exist.
