Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454952, here are decompositions:

29 + 31454923 = 31454952
43 + 31454909 = 31454952
71 + 31454881 = 31454952
79 + 31454873 = 31454952
211 + 31454741 = 31454952
251 + 31454701 = 31454952
271 + 31454681 = 31454952
283 + 31454669 = 31454952

Showing the first eight; more decompositions exist.
