Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545684, here are decompositions:

37 + 545647 = 545684
43 + 545641 = 545684
67 + 545617 = 545684
151 + 545533 = 545684
157 + 545527 = 545684
163 + 545521 = 545684
211 + 545473 = 545684
241 + 545443 = 545684

Showing the first eight; more decompositions exist.
