Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501296, here are decompositions:

67 + 31501229 = 31501296
97 + 31501199 = 31501296
179 + 31501117 = 31501296
257 + 31501039 = 31501296
317 + 31500979 = 31501296
349 + 31500947 = 31501296
373 + 31500923 = 31501296
397 + 31500899 = 31501296

Showing the first eight; more decompositions exist.
