Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545842, here are decompositions:

53 + 545789 = 545842
83 + 545759 = 545842
131 + 545711 = 545842
179 + 545663 = 545842
191 + 545651 = 545842
233 + 545609 = 545842
263 + 545579 = 545842
293 + 545549 = 545842

Showing the first eight; more decompositions exist.
