Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545672, here are decompositions:

31 + 545641 = 545672
73 + 545599 = 545672
139 + 545533 = 545672
151 + 545521 = 545672
199 + 545473 = 545672
223 + 545449 = 545672
229 + 545443 = 545672
433 + 545239 = 545672

Showing the first eight; more decompositions exist.
