Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545626, here are decompositions:

5 + 545621 = 545626
17 + 545609 = 545626
47 + 545579 = 545626
83 + 545543 = 545626
149 + 545477 = 545626
197 + 545429 = 545626
239 + 545387 = 545626
359 + 545267 = 545626

Showing the first eight; more decompositions exist.
