Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31814, here are decompositions:

43 + 31771 = 31814
73 + 31741 = 31814
127 + 31687 = 31814
151 + 31663 = 31814
157 + 31657 = 31814
241 + 31573 = 31814
271 + 31543 = 31814
283 + 31531 = 31814

Showing the first eight; more decompositions exist.
