Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523154, here are decompositions:

61 + 523093 = 523154
193 + 522961 = 523154
211 + 522943 = 523154
271 + 522883 = 523154
283 + 522871 = 523154
367 + 522787 = 523154
397 + 522757 = 523154
601 + 522553 = 523154

Showing the first eight; more decompositions exist.
