Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569626, here are decompositions:

13 + 31569613 = 31569626
307 + 31569319 = 31569626
349 + 31569277 = 31569626
367 + 31569259 = 31569626
379 + 31569247 = 31569626
397 + 31569229 = 31569626
433 + 31569193 = 31569626
457 + 31569169 = 31569626

Showing the first eight; more decompositions exist.
