Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558662, here are decompositions:

13 + 31558649 = 31558662
29 + 31558633 = 31558662
43 + 31558619 = 31558662
173 + 31558489 = 31558662
193 + 31558469 = 31558662
199 + 31558463 = 31558662
229 + 31558433 = 31558662
263 + 31558399 = 31558662

Showing the first eight; more decompositions exist.
