Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454506, here are decompositions:

23 + 31454483 = 31454506
257 + 31454249 = 31454506
359 + 31454147 = 31454506
383 + 31454123 = 31454506
389 + 31454117 = 31454506
509 + 31453997 = 31454506
563 + 31453943 = 31454506
683 + 31453823 = 31454506

Showing the first eight; more decompositions exist.
