Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606808, here are decompositions:

67 + 31606741 = 31606808
97 + 31606711 = 31606808
127 + 31606681 = 31606808
151 + 31606657 = 31606808
157 + 31606651 = 31606808
229 + 31606579 = 31606808
271 + 31606537 = 31606808
379 + 31606429 = 31606808

Showing the first eight; more decompositions exist.
