Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482426, here are decompositions:

37 + 31482389 = 31482426
83 + 31482343 = 31482426
89 + 31482337 = 31482426
149 + 31482277 = 31482426
179 + 31482247 = 31482426
197 + 31482229 = 31482426
257 + 31482169 = 31482426
307 + 31482119 = 31482426

Showing the first eight; more decompositions exist.
