Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545342, here are decompositions:

13 + 545329 = 545342
103 + 545239 = 545342
139 + 545203 = 545342
181 + 545161 = 545342
199 + 545143 = 545342
211 + 545131 = 545342
313 + 545029 = 545342
379 + 544963 = 545342

Showing the first eight; more decompositions exist.
