Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558584, here are decompositions:

17 + 31558567 = 31558584
131 + 31558453 = 31558584
151 + 31558433 = 31558584
193 + 31558391 = 31558584
257 + 31558327 = 31558584
263 + 31558321 = 31558584
331 + 31558253 = 31558584
373 + 31558211 = 31558584

Showing the first eight; more decompositions exist.
