Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528806, here are decompositions:

5 + 31528801 = 31528806
83 + 31528723 = 31528806
109 + 31528697 = 31528806
137 + 31528669 = 31528806
173 + 31528633 = 31528806
193 + 31528613 = 31528806
227 + 31528579 = 31528806
233 + 31528573 = 31528806

Showing the first eight; more decompositions exist.
