Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548936, here are decompositions:

79 + 31548857 = 31548936
113 + 31548823 = 31548936
173 + 31548763 = 31548936
179 + 31548757 = 31548936
193 + 31548743 = 31548936
197 + 31548739 = 31548936
239 + 31548697 = 31548936
277 + 31548659 = 31548936

Showing the first eight; more decompositions exist.
