Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545228, here are decompositions:

67 + 545161 = 545228
97 + 545131 = 545228
139 + 545089 = 545228
199 + 545029 = 545228
331 + 544897 = 545228
349 + 544879 = 545228
367 + 544861 = 545228
421 + 544807 = 545228

Showing the first eight; more decompositions exist.
