Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545422, here are decompositions:

131 + 545291 = 545422
191 + 545231 = 545422
233 + 545189 = 545422
281 + 545141 = 545422
359 + 545063 = 545422
389 + 545033 = 545422
443 + 544979 = 545422
461 + 544961 = 545422

Showing the first eight; more decompositions exist.
