Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545154, here are decompositions:

11 + 545143 = 545154
13 + 545141 = 545154
23 + 545131 = 545154
37 + 545117 = 545154
61 + 545093 = 545154
67 + 545087 = 545154
97 + 545057 = 545154
131 + 545023 = 545154

Showing the first eight; more decompositions exist.
