Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494426, here are decompositions:

37 + 31494389 = 31494426
79 + 31494347 = 31494426
163 + 31494263 = 31494426
179 + 31494247 = 31494426
269 + 31494157 = 31494426
283 + 31494143 = 31494426
307 + 31494119 = 31494426
347 + 31494079 = 31494426

Showing the first eight; more decompositions exist.
