Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534362, here are decompositions:

19 + 31534343 = 31534362
29 + 31534333 = 31534362
61 + 31534301 = 31534362
131 + 31534231 = 31534362
163 + 31534199 = 31534362
179 + 31534183 = 31534362
193 + 31534169 = 31534362
241 + 31534121 = 31534362

Showing the first eight; more decompositions exist.
