Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482518, here are decompositions:

7 + 31482511 = 31482518
19 + 31482499 = 31482518
79 + 31482439 = 31482518
181 + 31482337 = 31482518
211 + 31482307 = 31482518
241 + 31482277 = 31482518
271 + 31482247 = 31482518
349 + 31482169 = 31482518

Showing the first eight; more decompositions exist.
