Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523136, here are decompositions:

7 + 523129 = 523136
43 + 523093 = 523136
193 + 522943 = 523136
283 + 522853 = 523136
307 + 522829 = 523136
349 + 522787 = 523136
373 + 522763 = 523136
379 + 522757 = 523136

Showing the first eight; more decompositions exist.
