Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545424, here are decompositions:

37 + 545387 = 545424
53 + 545371 = 545424
157 + 545267 = 545424
167 + 545257 = 545424
193 + 545231 = 545424
211 + 545213 = 545424
263 + 545161 = 545424
281 + 545143 = 545424

Showing the first eight; more decompositions exist.
