Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589892, here are decompositions:

23 + 31589869 = 31589892
31 + 31589861 = 31589892
73 + 31589819 = 31589892
181 + 31589711 = 31589892
199 + 31589693 = 31589892
233 + 31589659 = 31589892
281 + 31589611 = 31589892
331 + 31589561 = 31589892

Showing the first eight; more decompositions exist.
