Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534282, here are decompositions:

11 + 31534271 = 31534282
41 + 31534241 = 31534282
83 + 31534199 = 31534282
113 + 31534169 = 31534282
179 + 31534103 = 31534282
359 + 31533923 = 31534282
443 + 31533839 = 31534282
449 + 31533833 = 31534282

Showing the first eight; more decompositions exist.
