Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502702, here are decompositions:

3 + 31502699 = 31502702
13 + 31502689 = 31502702
43 + 31502659 = 31502702
139 + 31502563 = 31502702
163 + 31502539 = 31502702
271 + 31502431 = 31502702
331 + 31502371 = 31502702
349 + 31502353 = 31502702

Showing the first eight; more decompositions exist.
