Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454962, here are decompositions:

5 + 31454957 = 31454962
53 + 31454909 = 31454962
59 + 31454903 = 31454962
89 + 31454873 = 31454962
179 + 31454783 = 31454962
281 + 31454681 = 31454962
293 + 31454669 = 31454962
311 + 31454651 = 31454962

Showing the first eight; more decompositions exist.
