Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558604, here are decompositions:

37 + 31558567 = 31558604
151 + 31558453 = 31558604
223 + 31558381 = 31558604
277 + 31558327 = 31558604
283 + 31558321 = 31558604
397 + 31558207 = 31558604
457 + 31558147 = 31558604
523 + 31558081 = 31558604

Showing the first eight; more decompositions exist.
