Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620244, here are decompositions:

41 + 31620203 = 31620244
53 + 31620191 = 31620244
113 + 31620131 = 31620244
137 + 31620107 = 31620244
251 + 31619993 = 31620244
263 + 31619981 = 31620244
401 + 31619843 = 31620244
443 + 31619801 = 31620244

Showing the first eight; more decompositions exist.
