Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547796, here are decompositions:

13 + 31547783 = 31547796
47 + 31547749 = 31547796
89 + 31547707 = 31547796
103 + 31547693 = 31547796
113 + 31547683 = 31547796
167 + 31547629 = 31547796
179 + 31547617 = 31547796
239 + 31547557 = 31547796

Showing the first eight; more decompositions exist.
