Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454486, here are decompositions:

3 + 31454483 = 31454486
97 + 31454389 = 31454486
103 + 31454383 = 31454486
109 + 31454377 = 31454486
223 + 31454263 = 31454486
337 + 31454149 = 31454486
409 + 31454077 = 31454486
433 + 31454053 = 31454486

Showing the first eight; more decompositions exist.
