Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523558, here are decompositions:

19 + 31523539 = 31523558
37 + 31523521 = 31523558
97 + 31523461 = 31523558
139 + 31523419 = 31523558
151 + 31523407 = 31523558
211 + 31523347 = 31523558
229 + 31523329 = 31523558
307 + 31523251 = 31523558

Showing the first eight; more decompositions exist.
