Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534410, here are decompositions:

41 + 31534369 = 31534410
67 + 31534343 = 31534410
109 + 31534301 = 31534410
113 + 31534297 = 31534410
139 + 31534271 = 31534410
163 + 31534247 = 31534410
179 + 31534231 = 31534410
211 + 31534199 = 31534410

Showing the first eight; more decompositions exist.
