Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545642, here are decompositions:

43 + 545599 = 545642
109 + 545533 = 545642
193 + 545449 = 545642
199 + 545443 = 545642
271 + 545371 = 545642
313 + 545329 = 545642
439 + 545203 = 545642
499 + 545143 = 545642

Showing the first eight; more decompositions exist.
