Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502796, here are decompositions:

19 + 31502777 = 31502796
53 + 31502743 = 31502796
97 + 31502699 = 31502796
107 + 31502689 = 31502796
109 + 31502687 = 31502796
137 + 31502659 = 31502796
233 + 31502563 = 31502796
239 + 31502557 = 31502796

Showing the first eight; more decompositions exist.
