Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545132, here are decompositions:

43 + 545089 = 545132
103 + 545029 = 545132
109 + 545023 = 545132
229 + 544903 = 545132
271 + 544861 = 545132
373 + 544759 = 545132
409 + 544723 = 545132
433 + 544699 = 545132

Showing the first eight; more decompositions exist.
