Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494358, here are decompositions:

11 + 31494347 = 31494358
101 + 31494257 = 31494358
179 + 31494179 = 31494358
197 + 31494161 = 31494358
239 + 31494119 = 31494358
317 + 31494041 = 31494358
359 + 31493999 = 31494358
431 + 31493927 = 31494358

Showing the first eight; more decompositions exist.
