Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584830, here are decompositions:

7 + 31584823 = 31584830
61 + 31584769 = 31584830
73 + 31584757 = 31584830
127 + 31584703 = 31584830
163 + 31584667 = 31584830
223 + 31584607 = 31584830
229 + 31584601 = 31584830
271 + 31584559 = 31584830

Showing the first eight; more decompositions exist.
