Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501704, here are decompositions:

5 + 31501699 = 31501704
43 + 31501661 = 31501704
71 + 31501633 = 31501704
83 + 31501621 = 31501704
137 + 31501567 = 31501704
167 + 31501537 = 31501704
173 + 31501531 = 31501704
181 + 31501523 = 31501704

Showing the first eight; more decompositions exist.
