Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620054, here are decompositions:

17 + 31620037 = 31620054
41 + 31620013 = 31620054
61 + 31619993 = 31620054
73 + 31619981 = 31620054
101 + 31619953 = 31620054
211 + 31619843 = 31620054
233 + 31619821 = 31620054
283 + 31619771 = 31620054

Showing the first eight; more decompositions exist.
