Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483328, here are decompositions:

67 + 31483261 = 31483328
211 + 31483117 = 31483328
241 + 31483087 = 31483328
277 + 31483051 = 31483328
337 + 31482991 = 31483328
421 + 31482907 = 31483328
439 + 31482889 = 31483328
619 + 31482709 = 31483328

Showing the first eight; more decompositions exist.
