Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593170, here are decompositions:

61 + 31593109 = 31593170
73 + 31593097 = 31593170
139 + 31593031 = 31593170
199 + 31592971 = 31593170
211 + 31592959 = 31593170
223 + 31592947 = 31593170
337 + 31592833 = 31593170
373 + 31592797 = 31593170

Showing the first eight; more decompositions exist.
