Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501056, here are decompositions:

17 + 31501039 = 31501056
19 + 31501037 = 31501056
47 + 31501009 = 31501056
79 + 31500977 = 31501056
89 + 31500967 = 31501056
109 + 31500947 = 31501056
137 + 31500919 = 31501056
157 + 31500899 = 31501056

Showing the first eight; more decompositions exist.
