Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545042, here are decompositions:

13 + 545029 = 545042
19 + 545023 = 545042
79 + 544963 = 545042
139 + 544903 = 545042
163 + 544879 = 545042
181 + 544861 = 545042
229 + 544813 = 545042
271 + 544771 = 545042

Showing the first eight; more decompositions exist.
