Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532240, here are decompositions:

41 + 532199 = 532240
47 + 532193 = 532240
53 + 532187 = 532240
179 + 532061 = 532240
239 + 532001 = 532240
251 + 531989 = 532240
257 + 531983 = 532240
263 + 531977 = 532240

Showing the first eight; more decompositions exist.
