Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545138, here are decompositions:

7 + 545131 = 545138
109 + 545029 = 545138
211 + 544927 = 545138
241 + 544897 = 545138
277 + 544861 = 545138
331 + 544807 = 545138
367 + 544771 = 545138
379 + 544759 = 545138

Showing the first eight; more decompositions exist.
