Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545864, here are decompositions:

37 + 545827 = 545864
73 + 545791 = 545864
223 + 545641 = 545864
313 + 545551 = 545864
331 + 545533 = 545864
337 + 545527 = 545864
367 + 545497 = 545864
421 + 545443 = 545864

Showing the first eight; more decompositions exist.
