Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589742, here are decompositions:

5 + 31589737 = 31589742
11 + 31589731 = 31589742
31 + 31589711 = 31589742
59 + 31589683 = 31589742
83 + 31589659 = 31589742
109 + 31589633 = 31589742
131 + 31589611 = 31589742
181 + 31589561 = 31589742

Showing the first eight; more decompositions exist.
