Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501068, here are decompositions:

7 + 31501061 = 31501068
29 + 31501039 = 31501068
31 + 31501037 = 31501068
59 + 31501009 = 31501068
89 + 31500979 = 31501068
101 + 31500967 = 31501068
127 + 31500941 = 31501068
149 + 31500919 = 31501068

Showing the first eight; more decompositions exist.
