Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483294, here are decompositions:

131 + 31483163 = 31483294
197 + 31483097 = 31483294
233 + 31483061 = 31483294
317 + 31482977 = 31483294
347 + 31482947 = 31483294
461 + 31482833 = 31483294
587 + 31482707 = 31483294
653 + 31482641 = 31483294

Showing the first eight; more decompositions exist.
