Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561376, here are decompositions:

3 + 561373 = 561376
17 + 561359 = 561376
29 + 561347 = 561376
293 + 561083 = 561376
317 + 561059 = 561376
479 + 560897 = 561376
503 + 560873 = 561376
593 + 560783 = 561376

Showing the first eight; more decompositions exist.
