Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523240, here are decompositions:

71 + 523169 = 523240
131 + 523109 = 523240
191 + 523049 = 523240
233 + 523007 = 523240
251 + 522989 = 523240
281 + 522959 = 523240
293 + 522947 = 523240
353 + 522887 = 523240

Showing the first eight; more decompositions exist.
