Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454464, here are decompositions:

3 + 31454461 = 31454464
23 + 31454441 = 31454464
113 + 31454351 = 31454464
263 + 31454201 = 31454464
317 + 31454147 = 31454464
347 + 31454117 = 31454464
383 + 31454081 = 31454464
467 + 31453997 = 31454464

Showing the first eight; more decompositions exist.
