Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454512, here are decompositions:

29 + 31454483 = 31454512
71 + 31454441 = 31454512
191 + 31454321 = 31454512
263 + 31454249 = 31454512
293 + 31454219 = 31454512
311 + 31454201 = 31454512
389 + 31454123 = 31454512
431 + 31454081 = 31454512

Showing the first eight; more decompositions exist.
