Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545012, here are decompositions:

109 + 544903 = 545012
151 + 544861 = 545012
199 + 544813 = 545012
241 + 544771 = 545012
313 + 544699 = 545012
463 + 544549 = 545012
499 + 544513 = 545012
541 + 544471 = 545012

Showing the first eight; more decompositions exist.
