Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501706, here are decompositions:

7 + 31501699 = 31501706
37 + 31501669 = 31501706
73 + 31501633 = 31501706
139 + 31501567 = 31501706
307 + 31501399 = 31501706
373 + 31501333 = 31501706
487 + 31501219 = 31501706
727 + 31500979 = 31501706

Showing the first eight; more decompositions exist.
