Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545444, here are decompositions:

7 + 545437 = 545444
73 + 545371 = 545444
241 + 545203 = 545444
283 + 545161 = 545444
313 + 545131 = 545444
421 + 545023 = 545444
541 + 544903 = 545444
547 + 544897 = 545444

Showing the first eight; more decompositions exist.
