Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569276, here are decompositions:

17 + 31569259 = 31569276
19 + 31569257 = 31569276
29 + 31569247 = 31569276
43 + 31569233 = 31569276
47 + 31569229 = 31569276
83 + 31569193 = 31569276
107 + 31569169 = 31569276
139 + 31569137 = 31569276

Showing the first eight; more decompositions exist.
