Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589050, here are decompositions:

23 + 31589027 = 31589050
71 + 31588979 = 31589050
107 + 31588943 = 31589050
419 + 31588631 = 31589050
443 + 31588607 = 31589050
557 + 31588493 = 31589050
587 + 31588463 = 31589050
683 + 31588367 = 31589050

Showing the first eight; more decompositions exist.
