Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558596, here are decompositions:

29 + 31558567 = 31558596
67 + 31558529 = 31558596
107 + 31558489 = 31558596
127 + 31558469 = 31558596
163 + 31558433 = 31558596
197 + 31558399 = 31558596
269 + 31558327 = 31558596
313 + 31558283 = 31558596

Showing the first eight; more decompositions exist.
