Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501070, here are decompositions:

31 + 31501039 = 31501070
61 + 31501009 = 31501070
103 + 31500967 = 31501070
151 + 31500919 = 31501070
199 + 31500871 = 31501070
277 + 31500793 = 31501070
379 + 31500691 = 31501070
421 + 31500649 = 31501070

Showing the first eight; more decompositions exist.
