Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545744, here are decompositions:

13 + 545731 = 545744
97 + 545647 = 545744
103 + 545641 = 545744
127 + 545617 = 545744
193 + 545551 = 545744
211 + 545533 = 545744
223 + 545521 = 545744
271 + 545473 = 545744

Showing the first eight; more decompositions exist.
