Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558634, here are decompositions:

7 + 31558627 = 31558634
67 + 31558567 = 31558634
181 + 31558453 = 31558634
307 + 31558327 = 31558634
313 + 31558321 = 31558634
487 + 31558147 = 31558634
571 + 31558063 = 31558634
577 + 31558057 = 31558634

Showing the first eight; more decompositions exist.
