Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558524, here are decompositions:

5 + 31558519 = 31558524
61 + 31558463 = 31558524
71 + 31558453 = 31558524
197 + 31558327 = 31558524
241 + 31558283 = 31558524
271 + 31558253 = 31558524
313 + 31558211 = 31558524
317 + 31558207 = 31558524

Showing the first eight; more decompositions exist.
