Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545246, here are decompositions:

7 + 545239 = 545246
43 + 545203 = 545246
103 + 545143 = 545246
157 + 545089 = 545246
223 + 545023 = 545246
283 + 544963 = 545246
349 + 544897 = 545246
367 + 544879 = 545246

Showing the first eight; more decompositions exist.
