Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589462, here are decompositions:

61 + 31589401 = 31589462
103 + 31589359 = 31589462
109 + 31589353 = 31589462
211 + 31589251 = 31589462
769 + 31588693 = 31589462
859 + 31588603 = 31589462
991 + 31588471 = 31589462
1021 + 31588441 = 31589462

Showing the first eight; more decompositions exist.
