Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558484, here are decompositions:

31 + 31558453 = 31558484
103 + 31558381 = 31558484
157 + 31558327 = 31558484
163 + 31558321 = 31558484
277 + 31558207 = 31558484
337 + 31558147 = 31558484
421 + 31558063 = 31558484
487 + 31557997 = 31558484

Showing the first eight; more decompositions exist.
