Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620004, here are decompositions:

11 + 31619993 = 31620004
23 + 31619981 = 31620004
197 + 31619807 = 31620004
233 + 31619771 = 31620004
263 + 31619741 = 31620004
281 + 31619723 = 31620004
401 + 31619603 = 31620004
443 + 31619561 = 31620004

Showing the first eight; more decompositions exist.
