Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547936, here are decompositions:

3 + 31547933 = 31547936
19 + 31547917 = 31547936
97 + 31547839 = 31547936
103 + 31547833 = 31547936
229 + 31547707 = 31547936
307 + 31547629 = 31547936
379 + 31547557 = 31547936
397 + 31547539 = 31547936

Showing the first eight; more decompositions exist.
