Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628096, here are decompositions:

7 + 31628089 = 31628096
79 + 31628017 = 31628096
127 + 31627969 = 31628096
193 + 31627903 = 31628096
457 + 31627639 = 31628096
523 + 31627573 = 31628096
613 + 31627483 = 31628096
739 + 31627357 = 31628096

Showing the first eight; more decompositions exist.
