Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498708, here are decompositions:

5 + 31498703 = 31498708
149 + 31498559 = 31498708
167 + 31498541 = 31498708
179 + 31498529 = 31498708
191 + 31498517 = 31498708
239 + 31498469 = 31498708
281 + 31498427 = 31498708
359 + 31498349 = 31498708

Showing the first eight; more decompositions exist.
