Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498962, here are decompositions:

13 + 31498949 = 31498962
31 + 31498931 = 31498962
83 + 31498879 = 31498962
109 + 31498853 = 31498962
113 + 31498849 = 31498962
149 + 31498813 = 31498962
151 + 31498811 = 31498962
199 + 31498763 = 31498962

Showing the first eight; more decompositions exist.
