Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548520, here are decompositions:

17 + 548503 = 548520
19 + 548501 = 548520
31 + 548489 = 548520
59 + 548461 = 548520
61 + 548459 = 548520
67 + 548453 = 548520
79 + 548441 = 548520
97 + 548423 = 548520

Showing the first eight; more decompositions exist.
