Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558832, here are decompositions:

13 + 31558819 = 31558832
43 + 31558789 = 31558832
61 + 31558771 = 31558832
73 + 31558759 = 31558832
103 + 31558729 = 31558832
139 + 31558693 = 31558832
199 + 31558633 = 31558832
313 + 31558519 = 31558832

Showing the first eight; more decompositions exist.
