Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593164, here are decompositions:

67 + 31593097 = 31593164
181 + 31592983 = 31593164
193 + 31592971 = 31593164
241 + 31592923 = 31593164
331 + 31592833 = 31593164
367 + 31592797 = 31593164
487 + 31592677 = 31593164
523 + 31592641 = 31593164

Showing the first eight; more decompositions exist.
