Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545048, here are decompositions:

19 + 545029 = 545048
151 + 544897 = 545048
211 + 544837 = 545048
241 + 544807 = 545048
277 + 544771 = 545048
331 + 544717 = 545048
349 + 544699 = 545048
397 + 544651 = 545048

Showing the first eight; more decompositions exist.
