Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545146, here are decompositions:

3 + 545143 = 545146
5 + 545141 = 545146
29 + 545117 = 545146
53 + 545093 = 545146
59 + 545087 = 545146
83 + 545063 = 545146
89 + 545057 = 545146
113 + 545033 = 545146

Showing the first eight; more decompositions exist.
