Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545236, here are decompositions:

5 + 545231 = 545236
23 + 545213 = 545236
47 + 545189 = 545236
149 + 545087 = 545236
173 + 545063 = 545236
179 + 545057 = 545236
257 + 544979 = 545236
317 + 544919 = 545236

Showing the first eight; more decompositions exist.
