Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548550, here are decompositions:

7 + 548543 = 548550
17 + 548533 = 548550
29 + 548521 = 548550
31 + 548519 = 548550
47 + 548503 = 548550
61 + 548489 = 548550
89 + 548461 = 548550
97 + 548453 = 548550

Showing the first eight; more decompositions exist.
