Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458526, here are decompositions:

89 + 31458437 = 31458526
107 + 31458419 = 31458526
149 + 31458377 = 31458526
227 + 31458299 = 31458526
353 + 31458173 = 31458526
443 + 31458083 = 31458526
557 + 31457969 = 31458526
677 + 31457849 = 31458526

Showing the first eight; more decompositions exist.
