Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466282, here are decompositions:

19 + 31466263 = 31466282
31 + 31466251 = 31466282
61 + 31466221 = 31466282
109 + 31466173 = 31466282
139 + 31466143 = 31466282
163 + 31466119 = 31466282
181 + 31466101 = 31466282
193 + 31466089 = 31466282

Showing the first eight; more decompositions exist.
