Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545152, here are decompositions:

11 + 545141 = 545152
59 + 545093 = 545152
89 + 545063 = 545152
173 + 544979 = 545152
191 + 544961 = 545152
233 + 544919 = 545152
263 + 544889 = 545152
269 + 544883 = 545152

Showing the first eight; more decompositions exist.
