Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454944, here are decompositions:

41 + 31454903 = 31454944
71 + 31454873 = 31454944
107 + 31454837 = 31454944
263 + 31454681 = 31454944
293 + 31454651 = 31454944
317 + 31454627 = 31454944
431 + 31454513 = 31454944
461 + 31454483 = 31454944

Showing the first eight; more decompositions exist.
