Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620152, here are decompositions:

13 + 31620139 = 31620152
43 + 31620109 = 31620152
139 + 31620013 = 31620152
163 + 31619989 = 31620152
199 + 31619953 = 31620152
241 + 31619911 = 31620152
283 + 31619869 = 31620152
331 + 31619821 = 31620152

Showing the first eight; more decompositions exist.
