Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501326, here are decompositions:

5 + 31501321 = 31501326
13 + 31501313 = 31501326
23 + 31501303 = 31501326
79 + 31501247 = 31501326
97 + 31501229 = 31501326
107 + 31501219 = 31501326
127 + 31501199 = 31501326
317 + 31501009 = 31501326

Showing the first eight; more decompositions exist.
