Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501038, here are decompositions:

29 + 31501009 = 31501038
59 + 31500979 = 31501038
61 + 31500977 = 31501038
71 + 31500967 = 31501038
97 + 31500941 = 31501038
139 + 31500899 = 31501038
167 + 31500871 = 31501038
229 + 31500809 = 31501038

Showing the first eight; more decompositions exist.
