Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568204, here are decompositions:

7 + 31568197 = 31568204
97 + 31568107 = 31568204
163 + 31568041 = 31568204
223 + 31567981 = 31568204
463 + 31567741 = 31568204
487 + 31567717 = 31568204
523 + 31567681 = 31568204
601 + 31567603 = 31568204

Showing the first eight; more decompositions exist.
