Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558334, here are decompositions:

7 + 31558327 = 31558334
13 + 31558321 = 31558334
127 + 31558207 = 31558334
271 + 31558063 = 31558334
277 + 31558057 = 31558334
337 + 31557997 = 31558334
373 + 31557961 = 31558334
397 + 31557937 = 31558334

Showing the first eight; more decompositions exist.
