Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589026, here are decompositions:

47 + 31588979 = 31589026
83 + 31588943 = 31589026
179 + 31588847 = 31589026
317 + 31588709 = 31589026
347 + 31588679 = 31589026
353 + 31588673 = 31589026
383 + 31588643 = 31589026
419 + 31588607 = 31589026

Showing the first eight; more decompositions exist.
