Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559764, here are decompositions:

83 + 31559681 = 31559764
113 + 31559651 = 31559764
191 + 31559573 = 31559764
227 + 31559537 = 31559764
263 + 31559501 = 31559764
293 + 31559471 = 31559764
317 + 31559447 = 31559764
347 + 31559417 = 31559764

Showing the first eight; more decompositions exist.
