Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620062, here are decompositions:

3 + 31620059 = 31620062
43 + 31620019 = 31620062
73 + 31619989 = 31620062
109 + 31619953 = 31620062
151 + 31619911 = 31620062
193 + 31619869 = 31620062
241 + 31619821 = 31620062
349 + 31619713 = 31620062

Showing the first eight; more decompositions exist.
