Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559068, here are decompositions:

17 + 31559051 = 31559068
41 + 31559027 = 31559068
71 + 31558997 = 31559068
269 + 31558799 = 31559068
419 + 31558649 = 31559068
449 + 31558619 = 31559068
461 + 31558607 = 31559068
599 + 31558469 = 31559068

Showing the first eight; more decompositions exist.
