Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484948, here are decompositions:

7 + 31484941 = 31484948
37 + 31484911 = 31484948
109 + 31484839 = 31484948
127 + 31484821 = 31484948
151 + 31484797 = 31484948
331 + 31484617 = 31484948
379 + 31484569 = 31484948
487 + 31484461 = 31484948

Showing the first eight; more decompositions exist.
