Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501366, here are decompositions:

5 + 31501361 = 31501366
53 + 31501313 = 31501366
137 + 31501229 = 31501366
167 + 31501199 = 31501366
389 + 31500977 = 31501366
419 + 31500947 = 31501366
443 + 31500923 = 31501366
467 + 31500899 = 31501366

Showing the first eight; more decompositions exist.
