Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593342, here are decompositions:

29 + 31593313 = 31593342
43 + 31593299 = 31593342
89 + 31593253 = 31593342
149 + 31593193 = 31593342
233 + 31593109 = 31593342
311 + 31593031 = 31593342
331 + 31593011 = 31593342
349 + 31592993 = 31593342

Showing the first eight; more decompositions exist.
