Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462306, here are decompositions:

17 + 31462289 = 31462306
89 + 31462217 = 31462306
173 + 31462133 = 31462306
179 + 31462127 = 31462306
383 + 31461923 = 31462306
419 + 31461887 = 31462306
563 + 31461743 = 31462306
569 + 31461737 = 31462306

Showing the first eight; more decompositions exist.
