Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558952, here are decompositions:

13 + 31558939 = 31558952
109 + 31558843 = 31558952
163 + 31558789 = 31558952
181 + 31558771 = 31558952
193 + 31558759 = 31558952
211 + 31558741 = 31558952
223 + 31558729 = 31558952
433 + 31558519 = 31558952

Showing the first eight; more decompositions exist.
