Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589288, here are decompositions:

37 + 31589251 = 31589288
151 + 31589137 = 31589288
271 + 31589017 = 31589288
277 + 31589011 = 31589288
331 + 31588957 = 31589288
337 + 31588951 = 31589288
631 + 31588657 = 31589288
727 + 31588561 = 31589288

Showing the first eight; more decompositions exist.
