Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536608, here are decompositions:

79 + 31536529 = 31536608
109 + 31536499 = 31536608
127 + 31536481 = 31536608
211 + 31536397 = 31536608
421 + 31536187 = 31536608
547 + 31536061 = 31536608
661 + 31535947 = 31536608
787 + 31535821 = 31536608

Showing the first eight; more decompositions exist.
