Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576246, here are decompositions:

5 + 31576241 = 31576246
47 + 31576199 = 31576246
59 + 31576187 = 31576246
83 + 31576163 = 31576246
179 + 31576067 = 31576246
197 + 31576049 = 31576246
239 + 31576007 = 31576246
347 + 31575899 = 31576246

Showing the first eight; more decompositions exist.
