Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454412, here are decompositions:

23 + 31454389 = 31454412
29 + 31454383 = 31454412
61 + 31454351 = 31454412
149 + 31454263 = 31454412
163 + 31454249 = 31454412
191 + 31454221 = 31454412
193 + 31454219 = 31454412
211 + 31454201 = 31454412

Showing the first eight; more decompositions exist.
