Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454406, here are decompositions:

17 + 31454389 = 31454406
23 + 31454383 = 31454406
29 + 31454377 = 31454406
157 + 31454249 = 31454406
257 + 31454149 = 31454406
283 + 31454123 = 31454406
353 + 31454053 = 31454406
383 + 31454023 = 31454406

Showing the first eight; more decompositions exist.
