Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482366, here are decompositions:

17 + 31482349 = 31482366
23 + 31482343 = 31482366
29 + 31482337 = 31482366
59 + 31482307 = 31482366
73 + 31482293 = 31482366
89 + 31482277 = 31482366
109 + 31482257 = 31482366
137 + 31482229 = 31482366

Showing the first eight; more decompositions exist.
