Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454460, here are decompositions:

19 + 31454441 = 31454460
29 + 31454431 = 31454460
71 + 31454389 = 31454460
83 + 31454377 = 31454460
109 + 31454351 = 31454460
139 + 31454321 = 31454460
197 + 31454263 = 31454460
211 + 31454249 = 31454460

Showing the first eight; more decompositions exist.
