Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545372, here are decompositions:

43 + 545329 = 545372
211 + 545161 = 545372
229 + 545143 = 545372
241 + 545131 = 545372
283 + 545089 = 545372
349 + 545023 = 545372
409 + 544963 = 545372
601 + 544771 = 545372

Showing the first eight; more decompositions exist.
