Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548512, here are decompositions:

11 + 548501 = 548512
23 + 548489 = 548512
53 + 548459 = 548512
59 + 548453 = 548512
71 + 548441 = 548512
89 + 548423 = 548512
113 + 548399 = 548512
149 + 548363 = 548512

Showing the first eight; more decompositions exist.
