Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523144, here are decompositions:

47 + 523097 = 523144
113 + 523031 = 523144
137 + 523007 = 523144
197 + 522947 = 523144
257 + 522887 = 523144
263 + 522881 = 523144
317 + 522827 = 523144
383 + 522761 = 523144

Showing the first eight; more decompositions exist.
