Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545122, here are decompositions:

5 + 545117 = 545122
29 + 545093 = 545122
59 + 545063 = 545122
89 + 545033 = 545122
233 + 544889 = 545122
239 + 544883 = 545122
401 + 544721 = 545122
491 + 544631 = 545122

Showing the first eight; more decompositions exist.
