Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606814, here are decompositions:

3 + 31606811 = 31606814
61 + 31606753 = 31606814
73 + 31606741 = 31606814
103 + 31606711 = 31606814
157 + 31606657 = 31606814
163 + 31606651 = 31606814
271 + 31606543 = 31606814
277 + 31606537 = 31606814

Showing the first eight; more decompositions exist.
