Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466186, here are decompositions:

13 + 31466173 = 31466186
43 + 31466143 = 31466186
67 + 31466119 = 31466186
79 + 31466107 = 31466186
97 + 31466089 = 31466186
307 + 31465879 = 31466186
337 + 31465849 = 31466186
397 + 31465789 = 31466186

Showing the first eight; more decompositions exist.
