Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545420, here are decompositions:

163 + 545257 = 545420
181 + 545239 = 545420
277 + 545143 = 545420
331 + 545089 = 545420
397 + 545023 = 545420
457 + 544963 = 545420
523 + 544897 = 545420
541 + 544879 = 545420

Showing the first eight; more decompositions exist.
