Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501354, here are decompositions:

23 + 31501331 = 31501354
41 + 31501313 = 31501354
107 + 31501247 = 31501354
263 + 31501091 = 31501354
293 + 31501061 = 31501354
317 + 31501037 = 31501354
431 + 31500923 = 31501354
491 + 31500863 = 31501354

Showing the first eight; more decompositions exist.
