Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483020, here are decompositions:

17 + 31483003 = 31483020
29 + 31482991 = 31483020
43 + 31482977 = 31483020
47 + 31482973 = 31483020
73 + 31482947 = 31483020
113 + 31482907 = 31483020
131 + 31482889 = 31483020
181 + 31482839 = 31483020

Showing the first eight; more decompositions exist.
