Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494372, here are decompositions:

71 + 31494301 = 31494372
79 + 31494293 = 31494372
109 + 31494263 = 31494372
131 + 31494241 = 31494372
193 + 31494179 = 31494372
211 + 31494161 = 31494372
229 + 31494143 = 31494372
281 + 31494091 = 31494372

Showing the first eight; more decompositions exist.
