Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462814, here are decompositions:

3 + 31462811 = 31462814
7 + 31462807 = 31462814
43 + 31462771 = 31462814
67 + 31462747 = 31462814
211 + 31462603 = 31462814
223 + 31462591 = 31462814
241 + 31462573 = 31462814
283 + 31462531 = 31462814

Showing the first eight; more decompositions exist.
