Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528106, here are decompositions:

3 + 31528103 = 31528106
13 + 31528093 = 31528106
37 + 31528069 = 31528106
109 + 31527997 = 31528106
139 + 31527967 = 31528106
193 + 31527913 = 31528106
277 + 31527829 = 31528106
397 + 31527709 = 31528106

Showing the first eight; more decompositions exist.
