Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545194, here are decompositions:

5 + 545189 = 545194
53 + 545141 = 545194
101 + 545093 = 545194
107 + 545087 = 545194
131 + 545063 = 545194
137 + 545057 = 545194
233 + 544961 = 545194
257 + 544937 = 545194

Showing the first eight; more decompositions exist.
