Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545072, here are decompositions:

43 + 545029 = 545072
109 + 544963 = 545072
193 + 544879 = 545072
211 + 544861 = 545072
313 + 544759 = 545072
349 + 544723 = 545072
373 + 544699 = 545072
421 + 544651 = 545072

Showing the first eight; more decompositions exist.
