Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589784, here are decompositions:

7 + 31589777 = 31589784
11 + 31589773 = 31589784
13 + 31589771 = 31589784
47 + 31589737 = 31589784
53 + 31589731 = 31589784
73 + 31589711 = 31589784
101 + 31589683 = 31589784
151 + 31589633 = 31589784

Showing the first eight; more decompositions exist.
