Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498752, here are decompositions:

11 + 31498741 = 31498752
113 + 31498639 = 31498752
193 + 31498559 = 31498752
211 + 31498541 = 31498752
223 + 31498529 = 31498752
239 + 31498513 = 31498752
281 + 31498471 = 31498752
283 + 31498469 = 31498752

Showing the first eight; more decompositions exist.
