Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558626, here are decompositions:

7 + 31558619 = 31558626
19 + 31558607 = 31558626
59 + 31558567 = 31558626
97 + 31558529 = 31558626
107 + 31558519 = 31558626
137 + 31558489 = 31558626
157 + 31558469 = 31558626
163 + 31558463 = 31558626

Showing the first eight; more decompositions exist.
