Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484848, here are decompositions:

11 + 31484837 = 31484848
47 + 31484801 = 31484848
71 + 31484777 = 31484848
107 + 31484741 = 31484848
137 + 31484711 = 31484848
149 + 31484699 = 31484848
431 + 31484417 = 31484848
509 + 31484339 = 31484848

Showing the first eight; more decompositions exist.
