Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454922, here are decompositions:

13 + 31454909 = 31454922
19 + 31454903 = 31454922
41 + 31454881 = 31454922
113 + 31454809 = 31454922
139 + 31454783 = 31454922
181 + 31454741 = 31454922
241 + 31454681 = 31454922
269 + 31454653 = 31454922

Showing the first eight; more decompositions exist.
