Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169028, here are decompositions:

19 + 169009 = 169028
37 + 168991 = 169028
127 + 168901 = 169028
331 + 168697 = 169028
397 + 168631 = 169028
487 + 168541 = 169028
547 + 168481 = 169028
571 + 168457 = 169028

Showing the first eight; more decompositions exist.
