Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466136, here are decompositions:

17 + 31466119 = 31466136
29 + 31466107 = 31466136
47 + 31466089 = 31466136
73 + 31466063 = 31466136
83 + 31466053 = 31466136
137 + 31465999 = 31466136
157 + 31465979 = 31466136
257 + 31465879 = 31466136

Showing the first eight; more decompositions exist.
