Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501054, here are decompositions:

17 + 31501037 = 31501054
107 + 31500947 = 31501054
113 + 31500941 = 31501054
131 + 31500923 = 31501054
191 + 31500863 = 31501054
257 + 31500797 = 31501054
281 + 31500773 = 31501054
317 + 31500737 = 31501054

Showing the first eight; more decompositions exist.
