Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548542, here are decompositions:

23 + 548519 = 548542
41 + 548501 = 548542
53 + 548489 = 548542
83 + 548459 = 548542
89 + 548453 = 548542
101 + 548441 = 548542
149 + 548393 = 548542
179 + 548363 = 548542

Showing the first eight; more decompositions exist.
