Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483864, here are decompositions:

3 + 31483861 = 31483864
23 + 31483841 = 31483864
131 + 31483733 = 31483864
173 + 31483691 = 31483864
281 + 31483583 = 31483864
311 + 31483553 = 31483864
317 + 31483547 = 31483864
431 + 31483433 = 31483864

Showing the first eight; more decompositions exist.
