Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558022, here are decompositions:

3 + 31558019 = 31558022
61 + 31557961 = 31558022
103 + 31557919 = 31558022
211 + 31557811 = 31558022
373 + 31557649 = 31558022
421 + 31557601 = 31558022
499 + 31557523 = 31558022
631 + 31557391 = 31558022

Showing the first eight; more decompositions exist.
