Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494376, here are decompositions:

29 + 31494347 = 31494376
83 + 31494293 = 31494376
113 + 31494263 = 31494376
197 + 31494179 = 31494376
233 + 31494143 = 31494376
257 + 31494119 = 31494376
293 + 31494083 = 31494376
449 + 31493927 = 31494376

Showing the first eight; more decompositions exist.
