Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501306, here are decompositions:

3 + 31501303 = 31501306
59 + 31501247 = 31501306
107 + 31501199 = 31501306
269 + 31501037 = 31501306
359 + 31500947 = 31501306
383 + 31500923 = 31501306
443 + 31500863 = 31501306
509 + 31500797 = 31501306

Showing the first eight; more decompositions exist.
