Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558694, here are decompositions:

31 + 31558663 = 31558694
61 + 31558633 = 31558694
67 + 31558627 = 31558694
127 + 31558567 = 31558694
241 + 31558453 = 31558694
313 + 31558381 = 31558694
367 + 31558327 = 31558694
373 + 31558321 = 31558694

Showing the first eight; more decompositions exist.
