Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588764, here are decompositions:

71 + 31588693 = 31588764
107 + 31588657 = 31588764
157 + 31588607 = 31588764
241 + 31588523 = 31588764
271 + 31588493 = 31588764
281 + 31588483 = 31588764
293 + 31588471 = 31588764
397 + 31588367 = 31588764

Showing the first eight; more decompositions exist.
