Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559734, here are decompositions:

47 + 31559687 = 31559734
53 + 31559681 = 31559734
83 + 31559651 = 31559734
197 + 31559537 = 31559734
233 + 31559501 = 31559734
263 + 31559471 = 31559734
317 + 31559417 = 31559734
383 + 31559351 = 31559734

Showing the first eight; more decompositions exist.
