Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498024, here are decompositions:

17 + 31498007 = 31498024
83 + 31497941 = 31498024
197 + 31497827 = 31498024
227 + 31497797 = 31498024
251 + 31497773 = 31498024
317 + 31497707 = 31498024
353 + 31497671 = 31498024
557 + 31497467 = 31498024

Showing the first eight; more decompositions exist.
