Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454456, here are decompositions:

67 + 31454389 = 31454456
73 + 31454383 = 31454456
79 + 31454377 = 31454456
193 + 31454263 = 31454456
307 + 31454149 = 31454456
373 + 31454083 = 31454456
379 + 31454077 = 31454456
433 + 31454023 = 31454456

Showing the first eight; more decompositions exist.
