Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620246, here are decompositions:

17 + 31620229 = 31620246
23 + 31620223 = 31620246
37 + 31620209 = 31620246
43 + 31620203 = 31620246
79 + 31620167 = 31620246
107 + 31620139 = 31620246
137 + 31620109 = 31620246
139 + 31620107 = 31620246

Showing the first eight; more decompositions exist.
