Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483744, here are decompositions:

11 + 31483733 = 31483744
53 + 31483691 = 31483744
167 + 31483577 = 31483744
191 + 31483553 = 31483744
197 + 31483547 = 31483744
251 + 31483493 = 31483744
311 + 31483433 = 31483744
353 + 31483391 = 31483744

Showing the first eight; more decompositions exist.
