Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589754, here are decompositions:

17 + 31589737 = 31589754
23 + 31589731 = 31589754
43 + 31589711 = 31589754
47 + 31589707 = 31589754
61 + 31589693 = 31589754
71 + 31589683 = 31589754
193 + 31589561 = 31589754
241 + 31589513 = 31589754

Showing the first eight; more decompositions exist.
