Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468974, here are decompositions:

7 + 31468967 = 31468974
11 + 31468963 = 31468974
71 + 31468903 = 31468974
73 + 31468901 = 31468974
113 + 31468861 = 31468974
151 + 31468823 = 31468974
181 + 31468793 = 31468974
197 + 31468777 = 31468974

Showing the first eight; more decompositions exist.
