Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593212, here are decompositions:

19 + 31593193 = 31593212
103 + 31593109 = 31593212
181 + 31593031 = 31593212
229 + 31592983 = 31593212
241 + 31592971 = 31593212
379 + 31592833 = 31593212
433 + 31592779 = 31593212
439 + 31592773 = 31593212

Showing the first eight; more decompositions exist.
