Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483002, here are decompositions:

11 + 31482991 = 31483002
29 + 31482973 = 31483002
113 + 31482889 = 31483002
163 + 31482839 = 31483002
179 + 31482823 = 31483002
181 + 31482821 = 31483002
223 + 31482779 = 31483002
241 + 31482761 = 31483002

Showing the first eight; more decompositions exist.
