Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559526, here are decompositions:

59 + 31559467 = 31559526
79 + 31559447 = 31559526
83 + 31559443 = 31559526
109 + 31559417 = 31559526
113 + 31559413 = 31559526
263 + 31559263 = 31559526
307 + 31559219 = 31559526
337 + 31559189 = 31559526

Showing the first eight; more decompositions exist.
