Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454514, here are decompositions:

17 + 31454497 = 31454514
31 + 31454483 = 31454514
53 + 31454461 = 31454514
73 + 31454441 = 31454514
83 + 31454431 = 31454514
131 + 31454383 = 31454514
137 + 31454377 = 31454514
163 + 31454351 = 31454514

Showing the first eight; more decompositions exist.
