Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534426, here are decompositions:

3 + 31534423 = 31534426
83 + 31534343 = 31534426
179 + 31534247 = 31534426
227 + 31534199 = 31534426
239 + 31534187 = 31534426
257 + 31534169 = 31534426
347 + 31534079 = 31534426
353 + 31534073 = 31534426

Showing the first eight; more decompositions exist.
