Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545804, here are decompositions:

13 + 545791 = 545804
31 + 545773 = 545804
73 + 545731 = 545804
157 + 545647 = 545804
163 + 545641 = 545804
271 + 545533 = 545804
277 + 545527 = 545804
283 + 545521 = 545804

Showing the first eight; more decompositions exist.
