Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534342, here are decompositions:

41 + 31534301 = 31534342
71 + 31534271 = 31534342
101 + 31534241 = 31534342
173 + 31534169 = 31534342
239 + 31534103 = 31534342
263 + 31534079 = 31534342
269 + 31534073 = 31534342
383 + 31533959 = 31534342

Showing the first eight; more decompositions exist.
