Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558622, here are decompositions:

3 + 31558619 = 31558622
103 + 31558519 = 31558622
223 + 31558399 = 31558622
241 + 31558381 = 31558622
313 + 31558309 = 31558622
541 + 31558081 = 31558622
661 + 31557961 = 31558622
691 + 31557931 = 31558622

Showing the first eight; more decompositions exist.
