Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523178, here are decompositions:

157 + 523021 = 523178
307 + 522871 = 523178
349 + 522829 = 523178
367 + 522811 = 523178
421 + 522757 = 523178
499 + 522679 = 523178
541 + 522637 = 523178
577 + 522601 = 523178

Showing the first eight; more decompositions exist.
