Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526688, here are decompositions:

19 + 31526669 = 31526688
41 + 31526647 = 31526688
71 + 31526617 = 31526688
191 + 31526497 = 31526688
199 + 31526489 = 31526688
211 + 31526477 = 31526688
257 + 31526431 = 31526688
269 + 31526419 = 31526688

Showing the first eight; more decompositions exist.
