Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501324, here are decompositions:

3 + 31501321 = 31501324
11 + 31501313 = 31501324
233 + 31501091 = 31501324
263 + 31501061 = 31501324
347 + 31500977 = 31501324
383 + 31500941 = 31501324
401 + 31500923 = 31501324
461 + 31500863 = 31501324

Showing the first eight; more decompositions exist.
