Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620176, here are decompositions:

37 + 31620139 = 31620176
67 + 31620109 = 31620176
109 + 31620067 = 31620176
139 + 31620037 = 31620176
157 + 31620019 = 31620176
163 + 31620013 = 31620176
223 + 31619953 = 31620176
307 + 31619869 = 31620176

Showing the first eight; more decompositions exist.
