Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620050, here are decompositions:

13 + 31620037 = 31620050
31 + 31620019 = 31620050
37 + 31620013 = 31620050
61 + 31619989 = 31620050
97 + 31619953 = 31620050
139 + 31619911 = 31620050
181 + 31619869 = 31620050
229 + 31619821 = 31620050

Showing the first eight; more decompositions exist.
