Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545426, here are decompositions:

97 + 545329 = 545426
223 + 545203 = 545426
283 + 545143 = 545426
337 + 545089 = 545426
397 + 545029 = 545426
463 + 544963 = 545426
499 + 544927 = 545426
523 + 544903 = 545426

Showing the first eight; more decompositions exist.
