Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454244, here are decompositions:

23 + 31454221 = 31454244
43 + 31454201 = 31454244
47 + 31454197 = 31454244
53 + 31454191 = 31454244
83 + 31454161 = 31454244
97 + 31454147 = 31454244
127 + 31454117 = 31454244
163 + 31454081 = 31454244

Showing the first eight; more decompositions exist.
