Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498662, here are decompositions:

5 + 31498657 = 31498662
23 + 31498639 = 31498662
71 + 31498591 = 31498662
103 + 31498559 = 31498662
113 + 31498549 = 31498662
149 + 31498513 = 31498662
163 + 31498499 = 31498662
191 + 31498471 = 31498662

Showing the first eight; more decompositions exist.
