Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502706, here are decompositions:

5 + 31502701 = 31502706
7 + 31502699 = 31502706
17 + 31502689 = 31502706
19 + 31502687 = 31502706
47 + 31502659 = 31502706
149 + 31502557 = 31502706
167 + 31502539 = 31502706
173 + 31502533 = 31502706

Showing the first eight; more decompositions exist.
