Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498710, here are decompositions:

7 + 31498703 = 31498710
53 + 31498657 = 31498710
71 + 31498639 = 31498710
151 + 31498559 = 31498710
163 + 31498547 = 31498710
181 + 31498529 = 31498710
193 + 31498517 = 31498710
197 + 31498513 = 31498710

Showing the first eight; more decompositions exist.
