Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501162, here are decompositions:

71 + 31501091 = 31501162
101 + 31501061 = 31501162
239 + 31500923 = 31501162
263 + 31500899 = 31501162
353 + 31500809 = 31501162
389 + 31500773 = 31501162
443 + 31500719 = 31501162
449 + 31500713 = 31501162

Showing the first eight; more decompositions exist.
