Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543596, here are decompositions:

17 + 31543579 = 31543596
53 + 31543543 = 31543596
67 + 31543529 = 31543596
107 + 31543489 = 31543596
167 + 31543429 = 31543596
199 + 31543397 = 31543596
353 + 31543243 = 31543596
373 + 31543223 = 31543596

Showing the first eight; more decompositions exist.
