Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593356, here are decompositions:

13 + 31593343 = 31593356
43 + 31593313 = 31593356
103 + 31593253 = 31593356
163 + 31593193 = 31593356
373 + 31592983 = 31593356
397 + 31592959 = 31593356
409 + 31592947 = 31593356
433 + 31592923 = 31593356

Showing the first eight; more decompositions exist.
