Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589648, here are decompositions:

37 + 31589611 = 31589648
109 + 31589539 = 31589648
241 + 31589407 = 31589648
271 + 31589377 = 31589648
331 + 31589317 = 31589648
397 + 31589251 = 31589648
631 + 31589017 = 31589648
691 + 31588957 = 31589648

Showing the first eight; more decompositions exist.
