Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589018, here are decompositions:

7 + 31589011 = 31589018
61 + 31588957 = 31589018
67 + 31588951 = 31589018
211 + 31588807 = 31589018
457 + 31588561 = 31589018
547 + 31588471 = 31589018
577 + 31588441 = 31589018
619 + 31588399 = 31589018

Showing the first eight; more decompositions exist.
