Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483038, here are decompositions:

47 + 31482991 = 31483038
61 + 31482977 = 31483038
131 + 31482907 = 31483038
149 + 31482889 = 31483038
179 + 31482859 = 31483038
199 + 31482839 = 31483038
239 + 31482799 = 31483038
277 + 31482761 = 31483038

Showing the first eight; more decompositions exist.
