Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599420, here are decompositions:

31 + 31599389 = 31599420
67 + 31599353 = 31599420
71 + 31599349 = 31599420
79 + 31599341 = 31599420
107 + 31599313 = 31599420
113 + 31599307 = 31599420
173 + 31599247 = 31599420
227 + 31599193 = 31599420

Showing the first eight; more decompositions exist.
