Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501062, here are decompositions:

23 + 31501039 = 31501062
53 + 31501009 = 31501062
83 + 31500979 = 31501062
139 + 31500923 = 31501062
163 + 31500899 = 31501062
191 + 31500871 = 31501062
199 + 31500863 = 31501062
269 + 31500793 = 31501062

Showing the first eight; more decompositions exist.
