Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481404, here are decompositions:

11 + 31481393 = 31481404
83 + 31481321 = 31481404
167 + 31481237 = 31481404
173 + 31481231 = 31481404
197 + 31481207 = 31481404
233 + 31481171 = 31481404
281 + 31481123 = 31481404
293 + 31481111 = 31481404

Showing the first eight; more decompositions exist.
