Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589718, here are decompositions:

7 + 31589711 = 31589718
11 + 31589707 = 31589718
59 + 31589659 = 31589718
107 + 31589611 = 31589718
151 + 31589567 = 31589718
157 + 31589561 = 31589718
179 + 31589539 = 31589718
257 + 31589461 = 31589718

Showing the first eight; more decompositions exist.
