Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528196, here are decompositions:

103 + 31528093 = 31528196
127 + 31528069 = 31528196
199 + 31527997 = 31528196
229 + 31527967 = 31528196
283 + 31527913 = 31528196
367 + 31527829 = 31528196
379 + 31527817 = 31528196
409 + 31527787 = 31528196

Showing the first eight; more decompositions exist.
