Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506702, here are decompositions:

5 + 31506697 = 31506702
13 + 31506689 = 31506702
61 + 31506641 = 31506702
103 + 31506599 = 31506702
173 + 31506529 = 31506702
179 + 31506523 = 31506702
181 + 31506521 = 31506702
191 + 31506511 = 31506702

Showing the first eight; more decompositions exist.
