Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466258, here are decompositions:

7 + 31466251 = 31466258
37 + 31466221 = 31466258
139 + 31466119 = 31466258
151 + 31466107 = 31466258
157 + 31466101 = 31466258
367 + 31465891 = 31466258
379 + 31465879 = 31466258
409 + 31465849 = 31466258

Showing the first eight; more decompositions exist.
