Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502006, here are decompositions:

127 + 31501879 = 31502006
157 + 31501849 = 31502006
199 + 31501807 = 31502006
307 + 31501699 = 31502006
337 + 31501669 = 31502006
373 + 31501633 = 31502006
439 + 31501567 = 31502006
607 + 31501399 = 31502006

Showing the first eight; more decompositions exist.
