Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593372, here are decompositions:

29 + 31593343 = 31593372
59 + 31593313 = 31593372
73 + 31593299 = 31593372
179 + 31593193 = 31593372
199 + 31593173 = 31593372
263 + 31593109 = 31593372
379 + 31592993 = 31593372
389 + 31592983 = 31593372

Showing the first eight; more decompositions exist.
