Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545044, here are decompositions:

11 + 545033 = 545044
83 + 544961 = 545044
107 + 544937 = 545044
167 + 544877 = 545044
251 + 544793 = 545044
263 + 544781 = 545044
317 + 544727 = 545044
431 + 544613 = 545044

Showing the first eight; more decompositions exist.
