Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534058, here are decompositions:

7 + 31534051 = 31534058
79 + 31533979 = 31534058
109 + 31533949 = 31534058
139 + 31533919 = 31534058
211 + 31533847 = 31534058
229 + 31533829 = 31534058
337 + 31533721 = 31534058
397 + 31533661 = 31534058

Showing the first eight; more decompositions exist.
